Design research on coal mine waterproof gate
HE Feng-hua
Abstract：Aiming at the inrush of Ordovician limestone water in the cross-cut main roadway excavation in the-415m post group, the author introduces general situation of the mine project, and describes the principle of setting up mine waterproof gate, the determination of water pressure resistance level, and the calculation and verification method of structural parameters such as maximum embed depth and length of the wall. Combined with mine auxiliary transport, ventilation and other systems, the selection of waterproof gates is carried out; the technical difficulties during construction, and the use and maintenance methods of waterproof gates are expounded. Based on the mine hydrogeology and the state of surrounding rocks, combined with the design specifications of the current mine waterproof gate, a set of waterproof gate design method is proposed, which is in line with the concept of mine safe production, and it is of great significance for the design and production of mines.
