摘要
以孙疃煤矿104采区为例,在分析孙疃煤矿地质资料的前提下,将研究区内断裂分维值,含水层厚度,灰岩采芯率,底板砂岩率,有效隔水层厚度,底板总体抗压强度等6个因素作为影响底板突水的主要因素,运用灰色模糊评判法,建立突水危险性模型。对104区10煤层底板突出危险性进行综合分析。将研究区按突水危险性划分为突水安全区、突水相对安全区、突水威胁区和突水危险区。
Suntuan 104 mining area coal mine as an example,based on the analysis of Suntuan under the premise of coal mine geological data,the fracture fractal dimension value of study area,the thickness of the aquifer,limestone mining core rate,rate of floor sandstone,the effective thickness of water-resisting layer and base plate overall six factors such as the compressive strength as the main factors influencing the inrush,using the grey fuzzy evaluation method,the water inrush risk model is set up.In the 104 district 10 coal floor outburst danger for comprehensive analysis.Will according to water inrush risk in the study area is divided into water inrush safety,water inrush relative safety,water inrush threatened area and water inrush danger zone.
