本文对应城石膏矿近距离多矿层上行开采矿压进行了研究,探讨了上行开采时上覆岩层的活动规律及特点,分析了支承压力的分布及发展变化规律,提出了上行开采的合理间距,证实了应城石膏矿G_z—8石膏组上行开采的可行性。
In this paper, a study was conducted on the upward mining and mining pressure of the nearby gypsum mine in the city. The law and characteristics of the overlying strata during upward mining were discussed. The distribution and development of the bearing pressure were analyzed, and the reasonable spacing of ascending mining was proposed. The feasibility of the ascending mining of the G_z-8 gypsum group in the Yingcheng Gypsum Mine was confirmed.
