摘要
为研究新疆屯宝煤矿在采动影响下覆岩的移动规律,以1152工作面为研究对象,利用相似模拟试验,对该工作面回采过程中顶板垮落情况及周期来压规律进行了分析。试验结果表明：该工作面初次来压步距50 m,垮落高度13 m,垮距42 m,来压显现较剧烈,此后工作面每推进26~28 m出现一次周期来压,大小周期来压交替出现。研究成果对屯宝煤矿工作面安全、高效生产有一定的指导意义。
Study for treasure under the influence of the movement of the strata in Xinjiang Tunbao Coal Mine,at 1152 working face as the research object,using similar simulation test,the roof caving in the process of the mining face and periodic weighting rule are analyzed. Experimental results show that 50 m,where the first pressure step caving height of 13 m,down from 42 m,appeared to pressure is intense,after working face every advance 26 ~ 28 m,a periodic cycle size to appear alternately. Research results of the chariot treasure coal mining working face has a certain guiding significance to the safe and efficient production.
