矿井在掘进井巷工程中往往会遇到流沙层的问题,流沙在水力的作用下,如果施工处理不当会造成严重的安全事故,给井上建筑及井下工程带来安全隐患,通过分析当前的主要的施工及设计方法,对井巷工程中遇到的流沙层问题的治理方法进行了探讨,从而找到经济可行的过滤沙层的施工方法,同时提出了施工中应注意的问题,以期对今后的治理流沙层问题提供有效的借鉴经验。
Mine shaft excavation in the project will often encounter the problem of quicksand layer, quicksand in the hydraulic effect, if the construction is not properly handled will cause serious accidents, underground buildings and downhole engineering to bring the security risks, by analyzing the current main The construction and design methods are discussed to discuss the management methods of runoff and sand layer problems encountered in the shaft and gateway engineering so as to find an economically feasible construction method of the filter sand layer and at the same time put forward some problems that should be paid attention to in the construction so as to improve the future Management of quicksand layer to provide effective lessons learned.
