巷道工程,由开工到竣工,要完成掘进、支护、铺轨、挖水沟、架机车滑走线、架照明线和铺设管道等七项分部工程。这七项工程的施工次序按地质、涌水情况、巷道规格尺寸、施工设备及操作技术等条件,大致可以构成以下三种方式:一种是单项施工方式。它是把一条巷道的上述各项分部工程,安排在不同时间先后进行施工。从时间上讲是分段的间歇施工,从施工项目上看,是单一逐
Roadway engineering, from the start of construction to completion, to complete the digging, support, track laying, dredging ditch, locomotive slide lines, lighting lines and laying pipelines and other seven sub-projects. The construction sequence of these seven projects can be divided into the following three ways according to the conditions of geology, gushing water, size of the roadway, construction equipment and operating techniques. One is a single construction method. It is to arrange the construction of the above-mentioned divisions of a roadway at different times. In terms of time, it is a segmented intermittent construction. From the perspective of the construction project, it is a single operation.
