摘　　要：五轮山煤矿1801工作面为矿井的第一个综采工作面,研究其顶板的矿压规律对开采过程中的顶板管理显得尤为重要。通过现场的仪器监测,结合矿山压力与岩层控制理论,对五轮山煤矿1801综放工作面回采期间矿压规律进行观测分析。得出了1801工作面回采期间的矿压显现规律和支架的载荷分布特点;来压期间,根据超前支承压力的观测,确定工作面超前支护的距离是50m。As the first fully mechanized coal mining face in Wulunshan coal mine, research on the rock pressure behavior of the roof was very important to the roof management in mining process. Based on in - situ instrument monitoring, and combining with theories of rock pressure and strata control, the rock pressure law during the exploitation of No. 1801 fully mechanized top - coal caving face was analyzed. The rock pressure behavior law and load distribution characteristics of the support during the exploitation of 1801 face were obtained. According to the observation of the advance abutment pressure during the face weighting, the forepoling distance was determined to be 50m.
