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。
以孫疃煤礦104採區為例,在分析孫疃煤礦地質資料的前提下,將研究區內斷裂分維值,含水層厚度,灰巖採芯率,底闆砂巖率,有效隔水層厚度,底闆總體抗壓彊度等6箇因素作為影響底闆突水的主要因素,運用灰色模糊評判法,建立突水危險性模型。對104區10煤層底闆突齣危險性進行綜閤分析。將研究區按突水危險性劃分為突水安全區、突水相對安全區、突水威脅區和突水危險區。
이손탄매광104채구위례,재분석손탄매광지질자료적전제하,장연구구내단렬분유치,함수층후도,회암채심솔,저판사암솔,유효격수층후도,저판총체항압강도등6개인소작위영향저판돌수적주요인소,운용회색모호평판법,건립돌수위험성모형。대104구10매층저판돌출위험성진행종합분석。장연구구안돌수위험성화분위돌수안전구、돌수상대안전구、돌수위협구화돌수위험구。
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.
