破裂井壁中开切卸压槽的设计与工艺淮南矿业学院杨平，柯昌松，汪仁和，方兴华（安徽淮南市）大量的实测和模拟试验结果表明，因地层下沉而产生的附加力是导致井壁破裂的主要原因。治理工程经验也表明，单纯采取环向抗的槽钢井圈治理措施，难以长时间维持井壁的稳定与安全... Design and Process of Open Cut Pressure Vessel in Cracked Shaft Wall Huainan Mining Institute Yang Ping, Ke Changsong, Wang Renhe, Fang Xinghua (Huainan City, Anhui Province) The results of a large number of experiments and simulations show that the additional force due to subsidence of the formation is the result of The main reason for the wall rupture. The experience of management engineering also shows that it is difficult to maintain the stability and safety of the shaft wall for a long time simply by adopting ring well resistance measures.
