| 摘 要： | 为了科学考察和研究首分层开采对下部分层突出危险性的保护程度和范围,以焦作矿区演马庄矿为例,采用井下实际测定煤层瓦斯含量、压力、工作面突出危险预测钻屑指标相结合的综合方法,查明演马庄矿25092工作面在首分层开采后厚煤层下部分层在22 m范围内的瓦斯含量和压力均小于突出危险临界值,基本消除了突出危险性,可在此确定的范围内布置下分层采掘巷道,实现安全高效回采。

| Abstract: | For the scientific study of the protection to reduce the outburst risk of the first slice mining on the lower slice coal seams, taking the Yanmazhuang mine as an example, use the integrated approach that adopt the calculation combining the actual gas content, gas pressure, the index of drill cuttings, evaluation results show both No. 25092 coalfaces' gas content and pressure which within the scope of 22 m are under the critical value, so it's safe to mining roadway in that area, achieve the target of safe and efficient mining. |
