从1965年至1971年,湖南省锡矿山南矿先后发生了三次大面积地压活动。 近十年来,长沙矿山研究院和锡矿山矿务局等单位对该矿的地压活动规律及其控制方法进行了研究。 根据现场调查,以及应力和位移测量的结果,得出了地压活动发生机制的一般规律,并指出:产生大面积地压活动最主要的原因是采空区中矿柱的破坏和倒塌。 按所得的规律和该矿的采矿计划,文中讨论了用充填法控制地压活动的各种问题,并对充填控制压力的机理作了分析。 文末对充填法控制地压的效果作了综合评价。
From 1965 to 1971, there were three large-scale underground pressure activities in the south mine of tin mine in Hunan Province. In the recent ten years, Changsha Institute of Mines and the Bureau of Mining and Mineral Resources and other units investigated the law of underground pressure and its control methods. According to the field survey and the results of stress and displacement measurements, the general rule of the mechanism of ground pressure activity is obtained. It is pointed out that the main reason for the large-scale underground pressure activity is the destruction and collapse of pillar in goaf. According to the law and the mining plan of the mine, the paper discusses the various problems of using the filling method to control the ground pressure activities and analyzes the mechanism of filling control pressure. At the end of the article, the effect of filling pressure control was comprehensively evaluated.
