摘要
喀斯特矿床的矿井以岩溶水充水为主,由于喀斯特地貌下岩溶发育程度较高,且发育不均匀性造成矿井充水具有不均匀、突发性。为有效防范和遏制煤矿水害事故的发生,针对典型岩溶地区,以习水县某煤矿为例,基于可控源音频大地电磁法(CSAMT)开展地球物理勘探,查明该工作面的突水成因及水源,提出可行性防治水方案。
The Karst water-filled coal mines are mainly filled with Karst water.This is mainly due to high and uneven development of Karst landforms,which makes water-fill unexpected and random.In order to effectively prevent and curb the occurrence of coal mine water accidents,and gradually improve the safety of coal mines,it is very important to identify the distribution of groundwater in coal mines and the spatial distribution of water-conducting fractures are identified and water damage to make prevention and treatment plan plays for safe production of the mine.In view of this,a coal mine in Xishui County was as a typical example in Karst region.A geophysical exploration based on the Controlled Source Audio Magnetotelluric Method(CSAMT)was conducted to find out the cause of water inrush and the source of water inrush.A feasibility plan for water control was put forward,and discussions on the treatment plan were carried out.
