基于Surfer的煤层底板突水评价方法及其应用

Evaluation method of coal seam floor water inrush based on Surfer and its application

随着车集矿矿产资源向深部开采,矿区煤层底板水害问题愈发凸显。基于Surfer应用软件,结合AHP型脆弱性指数法,对研究区底板太原组石灰岩含水层突水威胁性进行评价。构建了3个分析层次及评价指标体系,确定了各影响因子的权重,根据自然分级法将突水评价区划分为脆弱区-相对安全区等5个分区。结果表明,评价结果与实际情况相对吻合,较为可靠。为车集矿制订专门的底板防治水方案提供了基础依据,同时也更新升级了底板水害评价的手段和方法。

As the mining mineral resources of the Juji Coal Mine are deepened,the problem of water damage in coal seam floor becomes more and more prominent.Based on Surfer application software and combined with AHP vulnerability index method,the threat of water inrush from the floor of Taiyuan formation limestone the research area was evaluated.Three analysis levels and evaluation index system were established,and the weight of each impact factor was determined.According to the natural classification method,from vulnerable to relative safe,the water inrush evaluation area was divided into five areas.The results show that the evaluation results are consistent with the actual situation and are relatively reliable.It provides a basis for the development of a special floor water prevention and control scheme for the Juji Coal Mine,and also updates the methods for the water damage assessment of the floor.
