摘要
通过对2103胶带巷相关地质及水文地质资料研究,采用物探、钻探、化探等技术手段,分析了北辛窑矿井含水层、隔水层的特征及断层的导水性,判断1064 m处水源为砂岩裂隙水。在距该巷左帮1060 m处施工一个73 m^(3)的大水仓,在该水仓中有针对性地施工了13个放水孔,将掘进面水导入左侧水仓内,从而加快放水进程,降低水位标高,消除掘进面的水患威胁,提前放水为后期掘进和回采创造有利条件,同时提出改造排水系统,确保巷道涌水及时排出工作面。
Based on the geological and hydrogeological data of 2103 belt trench,the characteristics of aquifer and aquifuge and the water conductivity of fault in Beixinyao Mine were analyzed by using geophysical,drilling and geochemical techniques,and the water source at 1064 m is sandstone fissure water.A 73 m^(3) large sump was constructed at 1060 m away from the left side of the roadway.In the sump,13 drainage holes were constructed to guide the head-on water into the left sump,so as to speed up the drainage process,reduce the water level elevation,eliminate the flood threat of head-on driving,and release water in advance,so as to create favorable conditions for later excavation and mining.At the same time,the drainage system was proposed to ensure the water inflow and safety of the roadway discharge the working face at the same time.
