Proposal of revision for transducers setup of Coal Mine Safety Regulatio

The paper proposed that wind transducers, air velocity transducers and methane transducers in intake airway should be setup for alarm of coal (rock) and gas outburst additionally, full scale methane transducers or high-low concentration methane transducers should be equipped in coal (rock) and gas outburst mines. It proposed that methane transducers should be setup on upper corner of coal face. It put forward that methane transducers should also be installed on self-moving hydraulic support, coal plough, bolt drill carriage, continuous miner, shuttle car, and so on; dust transducers should be setup on tunneling face, and temperature transducers should be placed on forcing fan. It also proposed that electromechanical chambers are forbidden to be setup in return airway; trolley locomotives are forbidden in highly gassy mines; mine-used special type explosion-proof electric locomotive with storage battery and mine-used explosion-proof diesel locomotive are forbidden to be used in return airway of coal (rock) and gas outburst mines; vehicular methane controller or portable methane alarm detector should be installed on mine-used explosion-proof diesel locomotive. It indicated that carbon monoxide alarm concentration 0.002 4%CO is alarm concentration influencing on human health, fire alarm of worked out section should adopt indicator of change of carbon monoxide concentration.
