摘要
随着采深的增加,平煤股份十矿动力灾害表现出突出一冲击特性。为了有效预测预报动力灾害,在煤与瓦斯突出预测方法基础上,增加了掘进巷道两帮、回采工作面两巷预测钻孔和预测指标,并且确定了预测指标的临界值,形成了突出一冲击动力灾害预测方法,且现场验证效果良好。
With the increasing of mining depth,dynamical catastrophe presents outburst and rock burst character in Pingdingshan No. 10 Coal Mine. Based on the prediction method of coal and gas outburst, prediction drilling holes and prediction indexes were added on both sides of drivage roadway,in return airway and haulage gateway of working face. Critical value of prediction index was ascertained, too. Prediction method of outburst and rock burst dynamical catastrophe was formed. Field testing showed that it has good effect.
