Abstract

Dahaize coal mine was located in Maowusu desert and the buried depth of coal seam was relatively large. The excavated main slope passed through the following stratums, such as Quaternary, Jurassic, Cretaceous, and so on. And the differences of rock mechanics characteristic were very obviously. In the article, the constructed well bores were analyzed. The rock mechanics characteristics of each layer were traced out. The engineering geological parameters of each layer were calculated comprehensively and the rock mass quality classification was obtained. The monolayer water inflow of aquifer was predicted by the horizontal long and narrow water corridor method. The result provided the basis to choose the reasonable drainage facilities for shaft excavation. According to the analysis comprehensively of hydrogeology and engineering geology characteristics of each layer, the optimal scheme of slope excavating was established.
