为了对煤层突出危险性进行有效预测,提出了连续流量法预测薛湖矿掘进期间突出危险性,阐述了该方法测试装置及测试步骤,并通过开展现场测试及实验室测试确定预测指标的临界值。结果表明,薛湖煤矿煤巷掘进使用连续流量法预测突出的安全值为96.32 L,研究结论对薛湖煤矿有针对性地采取防突措施、提高防突效率具有重要意义。
In order to effectively predict the outburst danger of coal seam, a continuous flow method is proposed to predict the outstanding risk during the excavation of Xuehu Mine. The testing device and testing procedures are described. The critical value of the predictive index is determined through on-site testing and laboratory testing . The results show that the projected safety value of continuous flow method for coal roadway excavation in Xuehu Mine is 96.32 L, and the conclusion of the study is of great significance to take measures to prevent outbursts and improve the efficiency of outburst prevention.
