摘　　要：结合煤矿的开采设计,根据其地质构造、煤层等采矿地质条件,在利用原有井筒和其它主要生产系统,保证现有生产系统正常安全运转的前提条件下,分析条带开采间隔煤柱的强度,论证开采的安全系数,对地表矿区铁路因工业广场保护煤柱局部开采后的影响进行分析,并根据矿区铁路的损害程度提出了相应的调整和维修措施.Based on the geological structure, the coal seam, the previous shaft and other major production systems, this paper combines the exploitation design of a coal mine to analyze the strength of interval coal pillar by using strip mining. And the precondition is that the existing production systems work safely. This paper also reasons the mining safety factor, analyzes and estimates the influence on railway in coal mine area which is raised by local exploitation of protective coal pillar in the industrial square, and puts forward corresponding adjustment and repair based on the degree of the damage.
