Coal mine gas explosion early warning protection device

Abstract

The invention belongs to the technical field of coal mine gas safety equipment and particularly relates to a coal mine gas explosion early warning protection device. The device comprises a detection module, a bag-type dust collector, a fan and a controller, wherein the detection module comprises a gas detector and a dust detector. In the prior art, when a coal mine is exploited, gas is attached to pulverized coal, the gas and the pulverized coal are discharged together through a ventilation system, the pulverized coal outside a mine overflows, the environment outside the mine is affected, humidity in the mine is high, adhesion of the pulverized coal is high, unsmooth ventilation or blockage of the ventilation system is easily caused, the concentration of the gas is easily caused to exceed the limit, and danger is easily caused. By arranging the bag-type dust collector, pulverized coal is convenient to collect, on one hand, the situation that excessive pulverized coal is discharged to pollute the environment and affect the working environment of workers on the ground is avoided, on the other hand, the situation that the pulverized coal is attached to a pipeline passing through the system is avoided, good ventilation of a mine is guaranteed, and safety of the workers under the mine is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of coal mine gas safety equipment, in particular to a coal mine gas explosion early warning and protection device. Background technique [0002] Mine gas is a general term for CH4-based toxic and harmful gases. It generally refers to biogas, and the gas referred to below refers to biogas. Gas is a colorless, tasteless, odorless, non-toxic gas, lighter than air, easy to gather at the top of the roadway or head up the mountain, it is flammable and explosive under suitable conditions, and can cause hypoxia and suffocation in high concentrations. The gas disaster is the first of the "five natural disasters" in coal mines, and is the most harmful. The gas control policy of "pumping first, then mining, monitoring and monitoring, and wind to determine production" must be strictly followed. In order to effectively prevent and control gas disasters in coal mines, it is necessary to arrange gas early warning devices ...

AI Technical Summary

Problems solved by technology

[0003] Most of the gas early warning devices in the prior art do not consider that the gas is attached to the pulverized coal during coal mine mining, and the gas and pulverized coal are discharged through the ventilation system together, causing the pulverized coal outside the mine to overflow, affecting the environment outside the mine, and the coal in the mine Humidity is high, and coal powder has strong adhesion, which can easily cause poor ventilation or blockage of the ventilation system, easily cause the gas concentration to exceed the limit, and easily cause danger
