摘 要
 礦井水文地質(zhì)條件是影響煤礦安全生產(chǎn)的重要因素。礦井水文地質(zhì)條件不清或者對(duì)礦井水防治不當(dāng)，造成的礦井突水會(huì)局部或全部淹沒(méi)礦井，導(dǎo)致巨大的生命和財(cái)產(chǎn)損失。總結(jié)各種地質(zhì)條件的特點(diǎn)和規(guī)律，尋求防治對(duì)策是減少生命和財(cái)產(chǎn)損失的重要舉措。經(jīng)過(guò)大量的地質(zhì)資料和數(shù)十年的開(kāi)采經(jīng)驗(yàn)，對(duì)中馬村礦水文地質(zhì)特征進(jìn)行分析和研究，中馬村井田水文地質(zhì)條件十分復(fù)雜，通過(guò)對(duì)含水層，隔水層，地下水補(bǔ)、徑、排等水文地質(zhì)條件及大氣降水，地表水，老空水，含水層水，導(dǎo)水通道等充水因素對(duì)礦井生產(chǎn)安全的影響，運(yùn)用水動(dòng)力學(xué)法和比擬法確定礦井涌水量。通過(guò)分析總結(jié)以上水文地質(zhì)條件及影響因素，礦井水的防治可以通過(guò)防治局部突水，加強(qiáng)老空水的防治，以及建立和完善防排水系統(tǒng)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.
