石壕矿副井立井井筒净径6.5米、荒径7.35米,全深(包括井底水窝25米)326.84米,自上而下穿过的岩层分别为厚88.7米、124.5米和113.64米的嘉陵江石灰岩、飞仙关泥岩和玉龙山灰岩。该井筒具有从井口起即为基岩、涌水量小与岩层压力小等特点。给施工提供了比较有利的条件。副井立井原已掘砌31米,1978年恢复建设后重新施工,即在对新组建的施工队伍进行培训的基础上,于1980年1月正式开始下井段施工,同年7月22日完成井筒所剩下的295.84米的掘砌施工任务。
Mine shaft mine shaft Shijia mine net diameter of 6.5 meters, 7.39 meters diameter, full depth (including the bottom of the aqueduct 25 meters) 326.84 meters, from top to bottom through the rock formations were 88.7 meters thick, 124.5 meters and 113.64 meters thick Jialingjiang limestone, Feixianguan mudstone and Yulongshan limestone. The wellbore has a bedrock from the wellhead, water inflow is small and the formation pressure is small and so on. To provide a more favorable conditions for construction. Auxiliary shaft wells have been dredging 31 meters, construction and reconstruction in 1978 after the resumption of construction, that is, the newly formed construction team training on the basis of formally started in January 1980 next well construction, the same year on July 22 to complete the wellbore The remaining 295.84 meters of digging construction tasks.
