一村庄保护煤柱留设实例

An Example of Coal Pillar Preservation in one Village

为了使地表建筑物、铁路、水体等免受地下采煤产生的沉降影响,留设保护煤柱是解决该问题的合理方案。本文以嵩山煤矿采区内王坡、雷坡为例,选用邻近采区的坍陷范围计算出上、下山采动角,应用垂直断面法和垂线法设计王坡、雷坡的保护煤柱,研究偃龙煤田区域的采动数据,为采区设计、采煤方法提供数据支撑。

In order to avoid the subsidence effect of underground coal mining,such as surface structures,railways and water bodies,the protection of coal pillars is a reasonable solution to this problem.This paper takes WANGPO and LEIPO as examples.The upper and lower mining angles are calculated by using the collapse area near the mining area.The vertical section method and vertical line method are used to design the protective coal pillars of WANGPO and LEIPO,and the mining data of YANLONG coalfield are studied.The data support is provided for the mining area design and coal mining methods.
