综采工作面过煤层夹矸变异区开采技术研究

Research on the Mining Technologies Used in Rapid Passing through Dirt Band-Variable Region in Fully Mechanized Working Face

通过大量试验研究,提出合理的综采工作面快速过夹矸变异区的爆破工艺,顺利解决了其中的煤矿开采难题,保持矿井产量稳定,实现均衡生产。通过技术攻关及施工实践,为矿山今后工作面快速过夹矸变异区提供了宝贵的经验,提高了矿山的科技水平。

This paper put forward reasonable blasting technology used in rapid passing through dirt band-variable region in fully mechanized working face, which successfully solved the difficult problems of coal mining in this region, keep the mine production stability and achieve balanced production through a large number of experimental study. The technical research and construction practice provided valuable experience for rapid passing through dirt band-variable region in fully mechanized working face and raise the level of the mining technology.
