鹿台山矿工作面煤壁稳定性研究

Study on Coal Wall Stability at Mining Working Face of Lutaishan Mine

工作面煤壁稳定性的研究,对于保障生产的安全进行有十分重要的意义。根据鹿台山矿实际情况,利用理论计算对煤壁的稳定性进行研究,针对矿井实际情况,可知增加支架阻力、加快推进速度及注浆加固煤壁可以有效降低煤壁所受压力,增强煤壁稳定性,为控制煤壁片帮提供理论依据。

Study on coal wall stability at mining working face is of important significance to ensure the safe production. According to the actual situation of Lutaishan Mine, this paper studied coal wall stability by theoretical calculation. In view of the mine＇s actual situation, it was known that the increase in the support resistance, the rise in the developing speed and the grouting reinforcement of coal wall can effectively reduce the pressure on the coal wall and enhance the coal wall stability, providing theoretical basis for the control of rib fall of coal walls.
