Mining, digging, transporting, supporting and ventilation integrated intelligent mining technology

Abstract

The invention discloses a mining, digging, transporting, supporting and ventilation integrated intelligent mining technology. The working surface arrangement manner is simplified, so that the tunneling work amount of a half-coal-rock tunnel is reduced effectively; and unmanned working surface mining with mining, digging, transporting, supporting and ventilation coordinated control is realized through automatic devices such as a double-drum coal cutter, a scraper conveyer capable of realizing right-angle turning, an automatic loading and unloading type support, a telescopic air duct and the like. Compared with traditional mining, the technology has the characteristics of simple working surface arrangement, low roadway tunneling rate, high coal production rate, high device automation degree,safe, capability of realizing efficient and intelligent mining and the like and has the broad popularization and application prospects.

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
