Abstract

The invention relates to a safe delivery system applied to downhole coal bed gas (gas) in coal mining. A monitoring device, an automatic powder spraying and explosion suppression device and a fire retarding device are sequentially arranged on a delivery pipeline along the coal bed gas delivery direction, the automatic powder spraying and explosion suppression device is connected with a controller, and output ends of the monitoring device and the controller are connected with a monitoring system on the ground through information data buses and communication interfaces respectively. By the safe delivery system, information like methane, carbon oxide, temperature and flow in the delivery pipeline is monitored at any time; once the circumstance of limit exceeding is found, an alarm is given timely, and the circumstance is transmitted to a control center on the ground and even a national safety monitoring center. Once a fire disaster occurs, the disaster is controlled within a certain range under action of the fire retarding device and the automatic powder spraying and explosion suppression device.

Description

technical field [0001] The invention relates to a coalbed methane (gas) safe delivery system, in particular to an underground coalbed methane (gas) safe delivery system applied in coal mining. Background technique [0002] The gas concentration in the underground coalbed methane (gas) drainage pipeline is usually within the range of the gas explosion range. When the ground permanent or underground mobile drainage system uses wet drainage pumps for drainage, the gas concentration in the pipeline is There is no requirement, because of the negative pressure drainage, generally speaking, it is impossible for the gas to leak from the inside of the pipe to the outside of the pipe, but it is only possible for the air to enter the pipe from the outside of the pipe, so as to reduce the concentration of gas extraction, especially the sealing of holes on the mining face Lack of tightness, coal seam changes, etc., caused a large amount of air to be drawn into the pipeline, resulting in ...
