Monitoring method of coal mine safety monitoring system

Abstract

The invention discloses a monitoring method of a coal mine safety monitoring system, and belongs to the technical field of coal mining. The monitoring method of the coal mine safety monitoring system comprises the following steps of installing a set of carrier communication device on a coal mining machine, and connecting the carrier communication device to a pilot starting loop of the coal mining machine to form a self-protection loop so that signals are fed back to the upper-level three-machine controller; setting a pair of feedback points aiming at the coal mining machine in a host of the controller; establishing communication with the three-machine controller through a main system, and setting parameters such as starting delay and associated equipment of the coal mining machine in the main system; connecting the main system a looped network, transmitting data to a dispatching room through the looped network, and achieving remote one-key start and stop. According to the method, the coal mining machine which does not have a remote power transmission function originally has the remote power transmission function, labor cost is reduced, the coal mining machine has remote deenergizing function such as power outage in case of failures and emergency shutdown, and potential accidents are reduced.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a monitoring method for a coal mine safety monitoring system. Background technique [0002] Coal mining is the separation of valuable coal from the ground or surface and transported off site. Regardless of open-pit mining or underground mining, geological exploration must first be carried out to find out the distribution range of coal-bearing strata, the number of recoverable layers, layer thickness, dip angle, reserves, geological structure, spontaneous combustion tendency, water, gas, etc. Mining conditions, and then rationally plan the construction scale of the mining area, the number of mines, output and construction sequence. According to the overall design of the mining area and mine design, they will be handed over to production after construction one by one. Surface mining includes stripping and coal mining operations. The overlying rock is first stripped away to e...

Problems solved by technology

[0005] The purpose of the present invention is to provide a monitoring method for a coal mine safety monitoring system to solve the problem that the traditional coal shearer proposed in the above background technology does not have a remote power transmission function, and cannot perform remote power failure functions such as fault power failure and emergency shutdown. It can only carry out close-controlled operation, which has the problems of large labor costs and hidden dangers of accidents
