矿区地面建筑物采用留设有保护煤柱的方法予以保护,目前仍然是一个普遍的方法和有效措施。55年燃料工业部颁发的“矿区地面建筑物及主要井巷保护试行规程”中规定,在一定的条件下建筑物需留设保护煤柱进行保护。峰峰矿区地面建筑物保护煤柱是根据部规程规定的方法留设的,设计中采用的移动角则根据本矿区地表移动观测成果确定。但在生产实践中发现各种煤柱的保护效果并不一致,有的比
The protection of the ground buildings in the mining area by the method of leaving the pillar of protection coal is still a common method and effective measure. In the 55-year Ministry of Fuel Industry’s “Trial Provisions for the Protection of Ground Structures and Main Wells in Mining Areas” stipulated that under certain conditions buildings should be protected by the protection of coal pillars. Fengfeng mine ground building pillar protection is set aside according to the provisions of the Ministry of regulations, the design of the use of the moving angle of the mining area surface movement observed results to determine. However, in the practice of production, it is found that the protective effect of various coal pillars is not the same,
