Large Cross Section of Very Loose Gravel Layer Inclined Construction Support Technology Research

Very soft layer of gravel geological conditions in the mine construction has a serious impact on the efficient construction of the mine safety and personnel safety. Because the mining area where has no big development experience of the construction, the construction and development of mining face many difficult technical problems. For this passage we did some research by super support ,temporary support and permanent support technology for this problem, Ahead of the pipe roof support, U- shaped steel and backplane as the temporary support and reinforced concrete support as the permanent support of the roadway, the roadway can be passed the layer of the gravel easily. The construction technology can provide reference for the safe and efficient construction of the similar geological conditions.
