Idea on combined coal mining technology with multi coal shearers for longwall coal mining face

In this article,simply analyze and summarize complex mining attachment equipments and coal mining technology adopted on the present,introduce several coal mining methods adopted in the national coal mines,further give a theory reference for the national coal mines to choose complex mining equipments and coal mining methods.

Study and Practice on the Coal Mining Technology of the Rooms & Pillars Mining Mechanization Operated with Continuous Miners;

Multiple optimization method on mining technique of BAO-Yushan coal mine;

The paper shows the full mechanized technology is applied and researched in Handan mine area,improved the equipment,optimized the mining technique,gave full play to full mechanized efficienc

This article discussed the practice of technology system on safety and high efficiency from 6 aspects, including: synthetic control of gas, research of mining technique, new technique of supporting with bolts in coal roadways, new technique of geo-exploration, optimizing configuration of resource by adjusting work panels and faces, and building mines with high yield and high effect.

The mining craft of longwall mining method has many characteristics.

This Paper introduces building situation of high output and high efficiency and remarkable technical financial result from 1992,it makes modernized mining craft and coal production develop to high output and efficiency and high safety and high reliability with new technolog

The choice principle of mining craft way is pointed out.

In the paper, a multi-objective comprehensivc decision model of determining the optimal mining technology scheme for coalface is set up by using set-valued statistics principle and multi-objective decision method, and an applied example is given.

The attachment equipments and mining technology of coal face in the current coal mines are analyzed and summarized.

Based on the reality of the contiguous seam in the coal face of Sitai mine in Datong, this paper uses the theory of reliability, does an statistical analysis of every link operation in the craft system and has put foward the way of improving the reliability of the mining technique system.
