青龙寺煤矿5~(-2)煤层顶板含水层突水危险性评价
|
摘要
为评价青龙寺煤矿5-2煤层顶板含水层突水危险性,保证矿井的安全生产。文中利用地理信息系统(GIS)对影响煤层顶板直接充水含水层富水性的5个主控因素进行了分析,通过层次分析法(AHP),计算出各主控因素的权重值,构建了含水层富水性分区图;通过对导水裂隙带发育高度的计算,然后与5-2煤层顶板隔水岩段加以比较,建立了顶板冒裂安全性分区图;通过叠加含水层富水性分区图与顶板冒裂安全性分区图,建立了煤层顶板直接充水含水层突水危险性综合分区图。研究结果表明:在矿区西北、东北部和西南局部富水性较弱,东南部富水性较强;而顶板冒裂安全性在矿区中部和西南部处于冒裂非安全严重区,其他区域为冒裂非安全一般区。青龙寺煤矿5-2煤层顶板含水层突水危险性为:在矿区西北、东北和中部地区主要为相对安全区和较安全区,5-2煤层顶板含水层突水危险性较弱;在矿区西南和东南部地区主要为较危险区和危险区,5-2煤层顶板含水层突水危险性较强,从而对即将进行生产的5-20102和5-20104工作面煤层顶板水害防治方案的制定提供了科学依据。
In order to evaluate the risk of water inrush in roof aquifer of 5~(-2) coal seam in Qinglongsi Coalmine,and to ensure the safety of mine production.Five main control factors affecting water abundance of aquifers directly filled with water in coal seam roof are analyzed using Geographic Information System(GIS).The weights of each main control factor are calculated by Analytic Hierarchy Process(AHP),and the water-rich zone map of aquifer is constructed.By calculating the development height of water conduction fissure zone and comparing it with the roof water isolation rock section of 5~(-2) coal seam,the roof burst safety zoning map is established,and the water-rich zone map of aquifer and the roof burst safety zone map are superimposed,and the roof fracture safety zoning map is established by superposing the water-rich zone map of aquifer with the roof burst safety zoning map.The comprehensive zoning map of water inrush risk of directly water-filled aquifer in coal seam roof is established.The results show that the water abundance in the northwest,northeast and southwest of the mining area isweak and that in the southeast of the mining area is strong,while regarding the roof burst safety,the middle and southwest of the mining area is grave unsafe area.The rest of the area is a unsafe general area of crack.The risk of water inrush from roof aquifer of 5~(-2) coal seam in Qinglongsi Coalmine is as follows:the northwest,northeast and central areas of the mining area are mainly relative safe zone and safer zone with weaker danger.In the southwest and southeast,the danger is strong.Our study provides scientific basis for the formulation of the prevention and control scheme of the roof water disaster in the 5-20102 and 5-20104 working faces.
