Abstract

The invention discloses a rapid quantitative monitoring device for environmental parameters of a coal mine fire zone. The device comprises an infrared temperature sensing device, wherein the back part of the infrared temperature sensing device is connected with a rapid drill hole sealing device; the back end of the infrared temperature sensing device is connected with a detecting device; one end of a hose is connected with the back end of a hollow steel pipe, and the other end of the hose is connected with an inlet of an air room in the detecting device; the front fixed end of the rapid drill hole sealing device is connected with the back end of a floral tube which is sleeved outside the hollow steel pipe; an expansion capsule is arranged between the front fixed end and the back fixed end; a bearing, provided with a stationary shaft, is arranged in the fixed end; the stationary shaft is connected with the hollow steel pipe through external threads; and a rotating disk is connected with the hollow steel pipe behind the back fixed end through external threads. The rapid quantitative monitoring device is suitable for monitoring the temperature of an underground fire zone of a coal mine and concentrations of a plurality of index gases, and has the advantages of simple technique, comprehensive gas detection and reliability in parameter monitoring.

Description

technical field [0001] The invention relates to a device for monitoring environmental parameters in coal mine fire areas. Background technique [0002] When a fire occurs underground in a coal mine, when direct fire extinguishing is ineffective, it is necessary to seal the underground roadway or goaf to form a fire zone. It is very important to grasp the situation of the fire area in time for the formulation and implementation of fire control measures, and the temperature and H in the fire area 2 , O 2 , CO, CH 4 、C 2 h 2 、C 2 h 4 The gas concentration is the main index to judge the state of the fire area, so how to quickly and reliably monitor the environmental parameters of the fire area has always been a concern of technicians. At present, the existing environmental monitoring methods in fire areas mainly include drilling sampling and beam tube monitoring. The former is to drill holes into the fire area, manually collect gas samples and measure the temperature thr...
