摘要 对长沟煤矿工作面进行了实际矿压观测,包括顶煤初次垮落步距、直接顶岩层初次垮落步距、基本顶初次来压步距及其来压强度、基本顶周期来压步距及其来压强度,分析研究了采场矿压规律。 Through observing the practical mine pressure of Changgou mine's working face, including the pace of top coal collapsing initially, the pace of direct roof rock collapsing initially, the pace of basic top pressing initially and its intensity, and the pace of the basic top pressing periodically and its intensity, the paper has researched the rule of stope's mine pressure.
