摘要
华丰煤矿在1410工作面为了防治冲击地压,在防治过程中应用了顶底板断裂的应力解除法,对岩层应力解除参数选取及施工工艺进行实施,有效释放了工作面前方应力集中以及弹性能的积聚,缓解了工作面前方支承压力的积聚程度,为1410工作面的安全、高效开采提供了保障。
In order to prevent and control the bumping pressure in No.1410 coal mining face of Huafeng Mine,a stress releasing method with fracturing the seam roof and floor was applied in the prevention and control of the bumping pressure.The paper had an implement on the selection and construction technology on the strata stress releasing parameters,which had an effective releasing the stress concentration and the elastic energy accumulation at the front of the coal mining face and relaxed the support pressure accum...
