Abstract

The invention discloses a coal mine underground disaster risk safety monitoring and early warning device based on wireless communication. According to the coal mine underground disaster risk safety monitoring and early warning device, a plurality of groups of first monitoring mechanisms and a plurality of groups of second monitoring mechanisms are arranged, and the monitoring detection surfaces ofmonitoring assemblies of the first monitoring mechanisms all are arranged towards the roadway wall of a coal mine roadway in a faced mode so that the condition of air flow emitted from the roadway wall can be monitored emphatically, and the monitoring reliability is ensured; each group of second monitoring mechanisms comprises at least three monitoring assemblies, each of the monitoring detectionsurfaces of the three monitoring assemblies is arranged towards the direction away from the roadway wall, and the monitoring detection surfaces of the three monitoring assemblies are not arranged inparallel in pairs so that three-dimensional monitoring in different directions can be realized on the condition in the roadway, and the monitoring reliability and accuracy are ensured; and the coal mine underground disaster risk safety monitoring and early warning device has the advantages that the installation is simple and convenient, the angle adjustment is convenient, and the establishment andthe deployment and the control of a monitoring system are effectively ensured.

Description

technical field [0001] The invention relates to the technical field of coal mine mining, in particular to a wireless communication-based safety monitoring and early warning device for coal mine underground disaster risk. Background technique [0002] In recent years, coal mine gas explosion accidents have occurred frequently in various places, causing great losses to the life safety of the country and the people. The situation of coal safety production in my country is very severe. The inability to detect and monitor gas in a timely manner and with high sensitivity is the cause of excessive gas concentration in underground mines. An important cause of explosion accidents, so accurate and real-time monitoring of gas concentration is an important measure to prevent and reduce gas explosions. When it is necessary to use the safety monitoring and early warning devices for disaster risks in coal mines, since most of the existing monitoring and early warning devices are hand-held o...
