An integrated intelligent mining process for mining, transportation, branch and communication

Abstract

The invention discloses an intelligent mining technology integrating mining, transportation, support and communication, which effectively reduces the excavation engineering volume of semi-coal and rock roadways by simplifying the layout of the working face, adopts double-drum coal cutters, scraper conveyors that can turn at right angles, and automatic loading and unloading Automatic equipment such as vertical support and telescopic air duct realizes unmanned working face mining with coordinated control of mining, transportation and support; compared with traditional mining, this method has the advantages of simple working face layout, low roadway excavation rate, high coal recovery rate, and equipment automation. High, safe and efficient intelligent mining and other characteristics, has broad prospects for promotion and application.

Description

technical field [0001] The invention relates to the field of coal seam mining, in particular to an intelligent mining technology integrating mining, transportation, branching and communication. Background technique [0002] At present, the fully mechanized mining face needs to excavate at least two mining roadways and one cutting hole, and the roadway excavation rate is high; the mining equipment of the working face includes hydraulic supports, coal shearers, scraper conveyors, etc., and most of the workers work in places with serious dust and noise pollution. Working in the environment; many coal mines have entered deep mining, high ground stress, high temperature, high gas, etc. make the underground working environment unbearably hot and humid, and the risk of coal rock dynamic impact and gas outburst increases. Especially in the mining of thin and relatively thin coal seams, there are narrow working space, poor working conditions, high labor intensity, low safety level, l...

Problems solved by technology

[0002] At present, the fully mechanized mining face needs to excavate at least two mining roadways and one cutting hole, and the roadway excavation rate is high; the mining equipment of the working face includes hydraulic supports, coal shearers, scraper conveyors, etc., and most of the workers work in places with serious dust and noise pollution. Working in the environment; many coal mines have entered deep mining, high ground stress, high temperature, high gas, etc. make the underground working environment unbearably humid and hot, and the risk of coal rock dynamic impact and gas outburst increases

Especially in the mining of thin and relatively thin coal seams, there are narrow working space, poor working conditions, high labor intensity, low safety level, low yield per unit area of ​​the working face, poor economic benefits, fault structure and hard gangue have a great impact on mining, semi-coal and rock Difficulties in roadway excavation and tight excavation replacement have caused serious imbalances in the reserve-production ratio of thin and relatively thin coal seams
