摘要: 根据淮北矿业集团孙疃煤矿10煤层地质的实际赋存情况,利用岩梁结构理论对煤层顶板的运移规律进行了理论分析,并利用现场的矿压观测数据,对理论分析结果进行检验,理论计算和现场观测结果基本相符,从而理论计算可以为指导工作面安全生产提供科学依据。
关键词: 来压步距, 矿压显现, 支承压力
Abstract: According to the actual geological situation of 10 coal stata in sun tuan coal mine of HuaiBei Mining Group,this paper analysised the migration law of the 10th coal seam roof using rock beam theory, and tested the theoretical analysised results making use of the data from field observation, as a result,theoretical calculation accordanced with field observation. Theoretical calculation can provide a scientific basis for safety production of the mining face.
Key words: roof weighting step, strata behaviors, abutment pressure
