摘要
指出了目前主要以突水系数理论为依据进行带压开采安全危险性评价在实践应用中存在着重大缺陷.根据显水带、导水带及阻水储备带相对下组煤在空间上的赋存状况,总结归纳出7种带压开采判别模型,并提出了相应的具体防治水对策.通过原始导高分带特点、显水带阻水带压并与阻水储备段共同抵御底板突水的理论,指导邢台东庞矿9103工作面采前带压开采条件综合勘探,成果资料说明符合7种带压开采判别模型中的两种模型,并采取了相应的防治水对策,使该工作面试采成功.说明采前根据7种带压开采模型预分析方法可行,安全性评价客观符合实际,防治水对策得当,对于类似条件矿区采煤工作面可以进行试采.
It was pointed out that safety evaluation of mining under high groundwater pressure based on water inrush coefficient theory is irrational. According to occurrence conditions of aquiferous zone, groundwater conducting zone and storage segment of water-resistance for lower group coal, seven types criterion models of mining under high pressure was concluded and corresponding groundwater hazards controlling policy was put forward. Work face 9103 of Dongpang Mine in Xingtai, Hebei Province belongs to two kinds of seven. Work face 9103 mined successfully by applying theory and method last year. It is proved that safety evaluation model of mining under high groundwater pressure above-mentioned is effective and worth to further popularizing and applying to other coal mines with similar conditions.
