往复式采煤工艺及综采设备选型研究

Study on Reciprocating Mining Technology and Selection of Fully Mechanized Mining Equipment

为解决传统后退式、前进式采煤方式回收率低、通风漏风严重、巷道掘进工作量大等问题,以1703工作面为例,在分析其地质、煤层等条件的基础上分析了传统采煤方式的优劣势,并基于往复式采煤方式完成采煤工艺及巷道布置设计、综采设备选型,为提升1703工作面的开采效率奠定基础。

In order to solve the problems of traditional backward and forward coal mining methods,such as low recovery rate,serious ventilation and air leakage,and large tunneling workload,1703 working face is taken as an example to analyze the advantages and disadvantages of traditional coal mining methods on the Basis of geological,hydrological and coal seam conditions.
