6 FAQs about [Is it allowed to use rock drills in coal lanes ]
What is a coal mine health and safety plan?
(a) Each operator of a coal mine shall prepare and submit for approval by the Coal Mine Health and Safety District Manager for the district in which the mine is located, a plan providing for the safety of workmen in each slope or shaft that is commenced or extended after June 30, 1971. The plan shall be consistent with prudent engineering design.
When does a coal mine need firefighting equipment?
On and after September 30, 1971, each operator of a coal mine shall provide an adequate supply of firefighting equipment which is adapted to the size and suitable for use under the conditions present on the surface at the mine. [36 FR 9364, May 22, 1971, as amended at 36 FR 13143, July 15, 1971]
How does blast hole drilling work?
In some underground coal mines, blast hole drilling creates holes in the coal seam. Explosives are then placed in these holes to break the coal into smaller, manageable pieces for extraction. This method is more commonly used in areas where the coal is embedded in hard rock.
How do you break up rock and access deep coal seams?
Drilling and blasting are still the most effective ways to break up rugged rock and access deep coal seams. This technique is about precision and control—especially when working hundreds of meters underground where space is tight, and safety is critical. So, what exactly happens?
What is a tunnel drilling rig?
Tunnel drilling rigs are the underground heroes of coal mining. These machines don’t just drill straight down—they can move at angles, curves, and even horizontal paths. That’s why they’re perfect for creating long underground tunnels, ventilation paths, and access roads.
Who regulates coal mining operations in the United States?
Until a State or Tribe demonstrates the ability to manage a regulatory program that complies with all SMCRA requirements (30 CFR Chapter VII), OSMRE is the primary regulator of coal mining operations in the United States.
