These signs make it much easier to identify unsupported roof. Pre-op of Roof Bolter Check cable 4 splices, 5 to end the shift Adequate cable for the shift Adequately hung Nicks, abrasions Pull from reel if necessary Check for accumulations Coal dust Spilled oil Grease Empty boxes, garbage, etc. Check fire suppression One in kitchen One in the front of the machine near the operator station Do not activate Check panic strips Check all three panic strips Start the machine and tap Check controls Ensure controls are self centered On some older machine, the cable reel lever may not self center Check for excessive play Keep linkage free from obstructions Check lights Report any lights that are out to foreman or mechanic Check tires Look for missing tire tread Check for tools Rock bar Hammer Torque wrench Probe Check suction Tramming/Place Change Ensure everyone is clear Check inch tram Check ATRS Raise ATRS and pressurize Be observant for broken pins, cracks, and bleed-offs Check for bleed-off Bleed-off is when the ATRS will not stay pressurized when against the roof Lower ATRS Check boom Check rotation Check suction Raise stab jack Turning the machine right and left, pull ample slack cable from reel Ensure gas tests have been made in face area before entering last open crosscut See workplace exam Get in kitchen Ensure entire body is in kitchen Keep all body parts inside kitchen Check cable reel to ensure that it is off Center machine in entry Stay as low as possible in the kitchen Beware this machine may teeter and roof out Look ahead for obstruction on travelway Overhead clearance Bottom obstructions Tramming Bolter from Inch Tram Controls Ensure cable reel is disengaged Locate last row of bolts Make visual assessment of cut Inch tram forward to last row of bolts Tram bolter so that the right rear corner is closer to the right rib Have roof control plan diagram showing the placement of the machine in the roof bolter cycle Position the drill head of the machine so it is within 4 feet of the last row of bolts or closer, and within 4 feet of the rib or closer Roof conditions will dictate the exact distance of the bolt spacings Drilling Test Hole Drill proper length test hole according to roof control plan You can always drill higher than the roof control plan requires Review approved roof control plan and/or mine policy for exact location of test holes Watch for steel to jump This comes with experience Jumping indicates bed separation Look, listen, and feel for changes in the roof This comes with experience Roof may sound drummy or hollow Drilling sound will change as you go through different laminations Measure test hole Drag tip of tape measure against side of hole while withdrawing Catches with the tip of the tape measure indicates separation or cracks Install proper length bolt and identify Mark test hole Paint test hole or bolt installed in test hole This allows people to know where test holes are located Leave test hole open and identify Optional, to install a correct size bolt Notify section foreman of roof defects to determine supplemental support if you are unsure Will determine course of action Determine the length of bolts All bolts must anchor in solid roof.  See roof control plan Drilling and Installing Bolts Visually examine the roof If roof is visually defective, do not sound Look for dribbling, cracks, cutters, clay veins, horsebacks, etc. Advance bolter not more than 4 foot from last row of bolts Do not expose yourself to unsupported roof Raise ATRS ATRS must make contact with the roof Properly position bolter Within 4 feet from the rib and the last row of bolts See diagram from he roof control plan on bolting sequence Set canopy and stab jack Make sure the canopy and stab jack are pressurized Take assembled bolt, bearing plate, and resin Sound roof Unless obviously bad Use suitable device to sound the roof Listen for drummy or hollow sound Keep all body parts away from the drill boom Lower drill head to bottom Place starter steel in chuck Raise head until bit contacts roof Drill steel must be straight or plumb to correctly drill your hole Remove your hand from the drill steel Slowly rotate steel until bit penetrates rock while raising the drill head Increase drill speed Increase up pressure so that steel penetrates rock without clogging Drill starter hole to proper depth Look and listen for changes in roof Lower drill head to bottom with slow rotation and remove starter steel Varies with type of steel Insert finishing steel in existing hole Insert pusher steel into chuck Allow finisher steel to drop and couple with the pusher steel Remove you hand from the drill steel Increase drill speed and pressure to drill the maximum depth Pusher steel must be marked to ensure the proper hole depth which is 1 inch deeper than the bolt to be installed Slow rotation Lower drill head to bottom Remove steels Do not put your hand or arm directly underneath a hole with steels in them Place steels in steel quiver Insert resin into hole Insert bolt with plate already assembled Using the boom, push bolt 1 inch from roof No rotation should be used at this point Drop boom Insert wrench Wrench may not be used with hex steels Seat wrench firmly on bolt Rotate maximum speed for recommended mix time Over mixing can be just as bad as under mixing.  Count by saying one thousand one, one thousand two, etc. Stop rotation and push to roof with maximum thrust Hold pressure for recommended hold time Spin time and hold thrust time are on each box of resin Drop boom with wrench First bolt in each cut must be torque See roof control plan Follow roof control plan for bolting sequence Following the pre-established roof control bolting sequence gives you maximum protection from your ATRS and already installed bolts Set bolter so that the right rear corner is closer to the right rib Have roof control plan diagram showing the placement of the machine in the roof bolter cycle Make gas test at intervals not to exceed every 20 minutes Extend line curtain as bolts are advanced Normally it is acceptable to have curtain up to the rear of bolter unless concentration  of methane requires the canvas to be closer Keeping an unsupported roof sign behind the curtain In low coal, it is very easy to accidentally travel unsupported roof.  These signs make it much easier to identify unsupported roof. Hang curtain to within 10 feet of face when bolting is concluded Normally it is acceptable to have curtain up to within 10 feet of face unless concentration of methane requires the canvas to be closer Makes the area safer for the scoop operator Bending 6 foot bolts Place bolt on slight angle with  head end on bottom Place knee on the crimp point Press with your knee Pull the end of the bolt upward until you reach 45 degree angle Pick the head of the end of the bolt up Place your knee on the crimp Press with your knee Pull the head end until you reach a 90 degree angle The bolt when pulled properly will appear like a "U" shape Install plate Bending 42 inch or similar bolts Place bolt end in square stock on the bolter designed for bending Slide bolt in to the desired length Push head end down toward bottom Stop when you have about a 25 degree bend Over bending will create drag while inserting bolt into hole.  This makes it very difficult to get the bolt inserted, and may result in hangers Install plate Installing a Control Rod Follow all procedures outlined in drilling and installing bolts, except using a bearing plate Install control rod at intervals not to exceed 100 feet in solid roof The installation of control rods are not required where full grouting can be observed at the intervals required in the roof control plan Install control rods at 50 foot intervals in subnormal roof Drill control rod hole to the same depth as normal roof bolt hole Determines if there are voids in the roof into which resin is being lost Drill control rod hole out of pattern Install a normal length bolt without a bearing plate This allows you to measure up into the hole for resin Insert the bolt to within 1 inch of roof Mix resin according to manufacturer recommendations Look for a show of resin at the bolt head Contact foreman if there is no show of resin Adverse or unusual roof conditions must always be reported to the foreman End of Shift Activities Assure danger unsupported roof signs are hung In low coal, it is very easy to accidentally travel unsupported roof. These signs make it much easier to identify unsupported roof. Hang line canvas to the second to last full row of bolts outby the face Tram bolter to supply cars Hang bolter cable, if necessary Check with foreman for further instructions Let foreman know what supplies are needed Inform foreman of any  roof changes/machine problems Load bolter with supplies Gather and remove any damaged resins and used bits Put bits in used bit container Dispose damaged resin in garbage container Review the MSDS sheet with the trainee Go to mantrip and conduct head count Travel outside Look for hazards in travelway  See entering mine Talk to cross shift bolters about conditions and bolter maintenance This could be in the section, on the travelway or outside Park mantrip in pit shop Set panic brake Shut light off Place on charge Go directly to shower house and tag out Put your light on charge Place methane spotter on charge Make notations on white board as needed Unusual/Non Routine Activities Gas detection 1 percent or greater Shut down De-energize your machine Notify foreman Follow foreman's instructions to make changes in the ventilation system Retest for gas prior to restarting Gas detection 1.5 percent of greater Shut down De-energize your machine Notify foreman De-energize power to the entire section Follow foreman's instructions to make changes in the ventilation system Retest for gas prior to restarting Installation of supplemental support Identify signs of roof failure in which supplemental support is necessary Danger area off  Get instructions from foreman Start bolting 8 feet outby in solid roof Position bolter to provide maximum protection with your ATRS Install supplemental supports according to plan Evaluate roof continuously during any supplemental support installation Monitor areas where supplemental supports were installed Areas inby or outby the supplemental area may need additional attention Firefighting and evacuation Roof bolter duties obtain; fire extinguishers, rock dust, and take to the intake side of the fire Quick response in attacking a fire lessens the possibility of the fire getting out of control
