摘要
为了降低郑州矿区煤炭生产期间突水的危险性,系统分析研究了郑州矿区致突模式和提出基于突水模式的防治对策.在分析郑州矿区历年21次突水案例的基础上,根据突水通道和突水水源将突水模式分别划分为3大类4个亚类和两大类.基于具体的突水模式,提出了具体的防治对策.研究结果表明,依据突水通道将突水模式划分为3大类,即断层致突型、褶皱致突型和采动裂隙致突型,再根据规模大小以及地层空间关系可分为4个亚类,分别为滑动构造顶板裂隙致突模式、大中型断层直接对接含水层型突水模式、大中型断层—隔水层厚度变薄型突水模式、小型断层致突模式.依据突水水源将突水模式划分为两类,分别为老空水致突模式和高水压含水层水致突模式,并指出电法(包括瞬变电磁和高密度电法)为各个致突模式防治的必选对策.
In order to reduce risks of water-inrush during coal production, water inrush modes are analyzed and countermeasures of the corresponding mode are put forward based on the systematical research. On the basis of 21 cases of coalmine accident which took place in Zhengzhou mining area, water-inrush mode is classified. According to channels, it can be divided into 3 categories and 4 sub-categories, respectively; Countermeasure are put forward in terms of corresponding mode of water inrush. The results indicate that three modes, which are fault-induced mode, fold-induced mode, and mining-fracture-induced mode, are classified according to channels of water inrush. Then according to the fault size and spatial relationships of strata, fault-induced mode is further divided into four sub-classes, which are roof-fissure-induced mode of slide tectonic, direct-docking-aquifer-induced mode in medium and large fault zone, thick- ness-thinning-aquifuge-induced mode in medium and large fault zone, and small-fault-induced mode, respectively. In addition, the water inrush mode is further divided into goal-water-induced mode and high-pressure-aquifer-induced mode. Besides, electronic methods, including transient electromagnetic method and high-density electric method, are the prerequisite countermeasure for the water-inrush mode.
