WHEN COAL WAS KING: Typical methane detector at the Rogers

Jan 21, 2019 · One of the great dangers of underground coal mining is the explosive power of methane gas and coal dust. Methane is commonly released from coal formations during mining. Historically methane gas explosions have been responsible for hundreds of coal mine catastrophes. The first mechanical gas detector was a safety lamp invented by Sir

Foam for coal dust suppression during underground coal

Jul 01, 2019 · 1. Introduction. Coal dust is one of the main hazards associated with coal mining (Fan and Yu, 2002, Kong et al., 2018, Ren et al., 2014), as it pollutes the underground working environment and threatens the physical and mental health of workers.During coal production, almost all operations can produce dust, including drilling, blasting, tunneling, coal extraction, roof falls, transportation
