房柱式机械化开采工艺应用

Application of Room and Pillar Mechanization Mining Technology

很多煤矿由于种种因素的限制不适宜使用长壁式采煤工艺,而在使用短壁式采煤工艺时又存在回采效率低等问题。为了有效的解决短壁式采煤工艺中存在的问题,本文结合晋华宫矿开采中存在的具体问题和改进工艺,阐述了晋华宫矿房柱式采煤工艺的应用,并将其和块切式采煤工艺对比分析,得出房柱式采煤工艺开采的范围相对较大,而且能够确保煤柱的回采率更高,使得工作面的产煤量能够进一步增加,具有较为广阔的应用前景。

Long-wall coal mining technology are not suitable for many coal mines due to various factors, however, there are problems such as low recovery efficiency when using short-wall coal mining technology. In order to effectively solve the problems of short-wall coal mining technology, combined with concrete problems and improving technology in the mining of Jinhuagong Colliery, the paper expounds the application of room and pillar mining technology in Jinhuagong Colliery and compares it with block-cut coal mining technology, then concludes that the mining scope of room and pillar mining technology is relatively large,which can ensure higher recovery rate of coal pillar, increases coal production of the working face and has a broad application prospect.
