摘 要
 矿井水文地质条件是影响煤矿安全生产的重要因素。矿井水文地质条件不清或者对矿井水防治不当，造成的矿井突水会局部或全部淹没矿井，导致巨大的生命和财产损失。总结各种地质条件的特点和规律，寻求防治对策是减少生命和财产损失的重要举措。经过大量的地质资料和数十年的开采经验，对中马村矿水文地质特征进行分析和研究，中马村井田水文地质条件十分复杂，通过对含水层，隔水层，地下水补、径、排等水文地质条件及大气降水，地表水，老空水，含水层水，导水通道等充水因素对矿井生产安全的影响，运用水动力学法和比拟法确定矿井涌水量。通过分析总结以上水文地质条件及影响因素，矿井水的防治可以通过防治局部突水，加强老空水的防治，以及建立和完善防排水系统等方法。

 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.
