Coal and rock dynamic disaster multi-parameter wireless monitoring comprehensive early-warning technology and method

Abstract

The invention discloses a coal and rock dynamic disaster multi-parameter wireless monitoring comprehensive early-warning technology and method. The technology and method involve a data acquisition unit, a data storage and processing unit and a comprehensive early-warning unit. According to the technology, on the basis of the advantage that an intelligent line supports a brand new wireless digital communication system with the high-precision positioning and wireless access capacity in a closed special environment by means of the internet of things and a communication technology, with a working face coal body physical signal as a basis, an underground coal mine gas concentration sensor, a coal body stress gauge, a top plate pressure monitoring system, a sound emitting and monitoring system, an electromagnetic radiation monitoring system, a microearthquake system and a sensor of the microearthquake system are in wireless docking with the intelligent line, an underground wireless monitoring early-warning associated equipment is researched, a coal and rock gas dynamic disaster wireless multi-parameter judgment method and coal and rock gas dynamic disaster wireless multi-parameter judgment indexes are established, a coal mine coal and rock gas dynamic disaster wireless multi-parameter remote monitoring and early-warning system is formed, and a coal mine coal and rock gas dynamic disaster wireless multi-parameter remote monitoring comprehensive early-warning platform is developed.

Description

technical field [0001] The invention relates to a multi-parameter wireless monitoring comprehensive early warning technology and method for coal rock dynamic disasters, belonging to the field of coal rock gas dynamic disaster monitoring and early warning. Background technique [0002] Coal is an important energy source in our country, accounting for about 67% of energy consumption in our country, which greatly affects the development of the national economy. According to my country's "Twelfth Five-Year Plan" development report, by the middle of this century, the proportion of coal in my country's primary energy structure will still hardly be less than 50%. Therefore, in the future, coal will continue to be the most important energy source in our country. [0003] In recent years, coal and gas outbursts and explosion accidents have occurred frequently in my country's coal mines, which have become the biggest hidden danger of coal mine safety production. And with the increas...

Problems solved by technology

However, since this method mostly uses wired transmission, it has a certain impact on safe production, and it cannot make real-time predictions on coal, rock and gas dynamic disasters in the mining face, so it has limited effect on on-site production
