采用“溜井-平硐”开拓工程的矿山,首先要探明工程地质情况。井壁若有不良地质构造(如断层、节理和裂隙等)的存在,在溜井使用过程中,会由于矿石的冲击、碰撞和腐蚀而造成井壁局部塌方而形成“棚矿”及其他生产事故。目前,溜井直径和地下硐室加大,工程地质情况影响更为显著。文献[1]介绍了陕西富平宝
The use of “Chute - Ping Cave ” to open up the project of the mine, we must first prove the geological conditions of the project. If there is any bad geological structure (such as faults, joints and fissures) in the wellbore, the wellbore will be partially collapsed due to the impact, collision and corrosion of the ore during the process of using the wellbore to form a “shed mine” and other Production accident. At present, the diameter of the slippery shaft and the underground chamber are enlarged, and the influence of engineering geological conditions is more significant.
