摘　　要：综放开采过程中矿压显现现象剧烈,有必要对综采放顶煤工作面矿山压力显现规律进行研究。对此,以石港15109工作面为研究背景,通过相似模拟试验与现场实测相结合的方法,分析综放工作面矿压显现规律,研究结果表明:15109工作面初次来压步距64m,周期来压步距平均15m,周期来压过程中来压程度呈现强弱交替现象,分析原因是因为主压关键层交替破断导致,研究结果能够对综放工作面矿压规律做出理论指导。In the process of fully mechanized caving mining,the phenomenon of pressure appearing is very serious.It is necessary to study the law of pressure appearing in fully mechanized caving top-coal face.,stone port of 15109 working face as the research background,through similar simulation experiment and field measurement,the method of combining analysis of rock pressure of full-mechanized caving mining face firstly,the research results show that the first step to pressure from 64 m,15109 face periodic weighting step away from an average of 15 m,periodic weighting to the degree of pressure during the process of present strength alternate phenomenon,analysis of the reason is that the main key stratum pressure fracture cause alternately,the results of the study can make theoretical guidance to mine pressure regularity of full-mechanized caving mining face.
