Figure 1 shows a schematic drawing of a typical roof bolting pattern in a coal mine entry. Recent advances in ground control technology have made a large amount of drilling data for roof bolting available for analysis. These data were obtained during normal roof bolt installation Development Of A Six Drillhead Roof Bolting Machine The six-drillhead roof and rib bolting machines were specifically designed for Foresight Energy to be used in their mine located in the Illinois Coal Basin.The initial two machines were shipped and are currently being used in production at the Williamson Energy-Mach Mining coal mine Sandstone Coal Mine Roof Reduction of risk from roof and side fall in Indian coal mines. Suitable drilling equipment for proper drilling of bore holes to install roof bolts in coal mine roof rock has remained a problem in Indian coal mines .Though coal drills can be used in coal roof drilling in sandstone roof with hand held coal drills pose major problems.
