煤矿避难硐室选址评价研究

Study on evaluation of location selection for coal mine refuge chamber

为最大限度为井下有效区域内的作业人员提供一个及时的、保证生存的、安全可靠的避难空间。以层次分析法为基础,构建了以煤矿避难硐室周边地质情况等7个评价因素为二级指标,围岩稳定性等20个评价子因素为三级指标的煤矿避难硐室选址评价指标体系。在基于层次分析法基本原理和评价流程的基础上,对赵楼煤矿避难硐室进行实例分析,得出其避难硐室选址较为合理。

In order to provide a timety, safe and reliable refuge space for the workers in the effective area of underground coal mine, the paper constructs an evaluation index system of location selection for coal mine refuge chamber based on AHP, which takes 7 evaluation factors as secondary index, such as the surrounding geology, and takes 20 sub-evaluation factors as third class index, such as the surrounding rock stability. On the basis of AHP rationale and evaluation procedure, a case study is carried out for refuge chamber in Zhaolou Coal Mine which indicates the location selection of refuge chamber is reasonable.
