中文摘要：
针对近距煤层安全开采这一问题,通过介绍目前国内外对近距离煤层开采方式、巷道布置方式及合理煤柱尺寸留设等方面的研究现状,指出目前近距离煤层安全开采研究中存在的问题。研究发现应结合理论与现场实际给出＂近距离煤层＂的确切定义;近距离煤层开采方式的选择应综合考虑到上煤层的上覆岩层性质与结构的作用;结合实验室相似模拟试验及数值计算模拟,充分考虑下煤层围岩性质及采动效应对合理煤柱尺寸留设影响的理论研究。
英文摘要：
We pointed out that there are some problems in close distance coal seams safe mining by introducing the study at home and abroad about mining method, roadway arrangement way, reasonable size of coal pillar, etc. We concludes that the definition of close distance coal seams is determined by the theoretical research and the actual data; the mining method selection should consider the synthetic effect of the properties and structure of upper coal seam overlying strata; the theoretical research of reasonable size of coal pillar should give full consideration to the properties of surrounding strata and mining effect of lower coal seam, combining with the similarity simulation experiment and numerical simulation of laboratory.
