一、工程概况 我矿小立沟矿区,开拓两个竖井,直径均为3米,主井为小立沟竖井,井口标高875米,井底标高604米,暂时掘到到642米。副井是东沟竖井,井口标高为745米,井底标高644米。小立沟矿区地质条件复杂,整个矿区受F_3F_4F_(29)三个断层的影响,形成构造影响带,在其影响下,岩石破碎,裂隙发育,溶蚀作用使裂隙加宽呈带状,构成了整个白云岩岩溶裂隙含水地层,裂隙带各段发育程度不均匀,溶蚀强弱不同,含透水性差异较大。小立沟竖井穿过含水层大约130米,
I. Project Overview Our mine is located in Xiaoligou Mining Area, and it has developed two vertical shafts with a diameter of 3 meters. The main shaft is a small vertical shaft with an elevation of 875 meters at the wellhead and an elevation of 604 meters at the bottom of the well. It is temporarily excavated to 642 meters. The auxiliary well is the Donggou shaft with an elevation of 745 meters and an elevation of 644 meters. The geological conditions of the Xiaoligou mining area are complex. The entire mining area is affected by three faults F_3F_4F_(29), forming a structural impact zone. Under the influence of the fault, the rock is fractured and the fracture develops. The dissolution causes the fracture to widen into a band, forming the entire In the dolomite karst fissured water-bearing strata, the development of the fractured sections is uneven, and the corrosion intensity is different. The water permeability is different. The small vertical shaft is about 130 meters through the aquifer.
