Some units are often the reasons for the lack of mountains in the professional and technical personnel, etc. and not on time.
(2)On the excessive pursuit of low-power components, under conditions of high humidity mines, methane, water vapor in the combustion element surface is easy to condense on the surface of components, reducing component life; (3)Poor ability to prevent poisoning; (4)The technological level of the carrier catalytic elements used by methane sensors is below standard which finally result in poor performance.
Solutions 3.1 Strengthen the Site Management and Maintenance Standard While national and provincial, and municipal administrations mandatory requirement of coal major, medium and small coal mines with high gas or gas outburst mine monitoring and control system must be equipped and increased the mine production safety management efforts, but some places state-owned mines, especially small township coal mines, due to the lack of professional and technical people Members which have not properly use the equipment and maintenance system, causing the system does not have the function of maintenance terminal device to become the bottleneck of the entire system, even a sensor connected with the system does not be adjusted.
