Every underground coal mining section in the United States operates under a MSHA-approved mine ventilation plan, which contains provisions for methane and dust control, as specified in 30 CFR 75.370. The dust control portion of the ventilation plan is specifically developed by the mine operator for each section in the mine and approved by the MSHA District Manager. Additional requirements for

As background, the Continuous Personal Dust Monitor currently in use in underground coal mining (Thermo Scientific PDM3700) has significantly improved respirable coal dust monitoring capabilities and compliance with MSHA coal mine dust exposure regulations and demonstrated the value in providing exposure information directly to the miner. By limiting solutions to a mass-based unit to meet

Heat related illnesses in the underground mining environment are an important safety and health matter that needs to be managed by the coal mining industry. The proper management of heat related illness will require individual operations to use risk analysis techniques to identify the hazards, and determine effective controls to allow coal mine workers to work safely in the underground

Many underground coal mines use some form of telephone as the primary means of communications between the surface and the underground miners. It is easy to imagine two phones (or transceivers, as introduced in Section 2.1.1) directly connected by wires to form the physical communications link. Relating to the previous discussion of Figure 2-2 in Section 2.1.1, the energy from the transmitter
