摘　　要：为解决小常煤矿30212工作面的三角煤回收难题,提高煤炭资源的回收率,通过对刀把面和扇形面两种开采方案进行技术经济比较,确定了工作面的扇形回采工艺,研究了扇形开采关键技术,并在现场进行了试验应用。结果表明:通过扇形开采技术的实施,回收三角煤16万t,结合矿压观测分析,也验证了该技术的可行性及适用性,为类似条件下的工作面开采提供了参考借鉴。In order to solve the problem of triangle coal recovery in the 30212 working face of Xiaochang Coal Mine and improve the recovery rate of coal resources, through the technical and economic comparison of two mining schemes of the knife handle face and the sector face, the sector mining technology of the working face is determined, and the key technology of sector mining is studied, and the test application is carried out in the field.The results show that 160 000 t of triangle coal is recovered through the implementation of sector mining technology.Combined with the observation and analysis of ore pressure, the feasibility and applicability of this technology are also verified, which provides a reference for mining in similar working face under similar conditions.
