本文论述了1976年7月28日唐山地震中开滦煤矿竖井井筒、井底车场、硐室、大巷、采区巷道、回采工作面和巷道支护等井巷工程的典型震害情况。分析表明井巷工程震害与工程地质条件、地质构造、围岩特征、支护形式、相关巷道、施工质量等直接有关。文中指出强烈地震使电源中断,并使井下涌水量成倍增加,淹没大量巷道和设备,产生了严重的次生灾害。文中并对地震区矿井井巷工程的设计和抗震措施提出了一些建议。
This paper discusses the typical seismic damage of the shaft and shaft in the Kailuan Mine in the Tangshan earthquake on July 28, 1976, such as the shaft shaft, the bottom hole yard, the underground chamber, the roadway in the mining area, the mining face and roadway support. The analysis shows that the damage of the shaft and gateway engineering is directly related to the engineering geological conditions, geological structure, surrounding rock characteristics, supporting forms, relevant tunnels and construction quality. The article pointed out that a strong earthquake caused the power supply to be interrupted, and the amount of underground water inflow doubled, flooding a large number of roadways and equipment, resulting in serious secondary disasters. In the paper, some suggestions are put forward for the design of mine shaft and tunnel engineering and seismic measures in the earthquake area.
