Abstract
The hydro-geological condition of coal mine is an important factor to affect safety production of the coal mine. It is unclear to the hydro-geological condition of coal mine or it is improper to prevent and control the mine water, the partial or total mine is drowned out by water bursting, and they cause tremendous losses in the lives and properties. This paper summarizes the characteristics and the laws of all geological conditions and seeks the prevention countermeasure so as to reduce the losses of life and property. This paper also analyses hydro-geological features of the Zhongma village mining according to large amounts of geological data and decades of mining experience. The hydro-geological conditions of Zhongma field are very complex, through to hydro-geological conditions including the water-bearing layer, the waterproof layer, the groundwater recharge, pathway, platoon and so on and filling factors including atmospheric precipitation, surface waters, the old air-water, the water-bearing stratum water, wicking passage and so on have an effect on the mine production safety and determines mine inflow using hydrodynamic method and analogue method. It may strengthen the prevention of the partial flooding and the old air-water as well as establish and consummate drainage system and so on to prevent mine water on the basis of summarizing and analyzing above hydro-geological conditions and their influencing factors.
Key words: hydro-geological conditions of coal mine;hydrodynamic method;analogue method;mine inflow
