摘 要:某煤矿7199工作面在回采过程中,顶板裂隙带导通煤层顶板砂岩水和石盒子组底界砂岩水,造成长期高水量涌水,几度危及工作面回采。为了实现7199工作面在高水压突水条件下安全回采,通过水质化验、水情观测、矿压观测分析等手段,确定水源和出水规律;通过分析工作面突水特征和涌水期间工作面顶板来压规律进行对比分析,找出了顶板压力和涌水之间的关系;利用岩层在周期来压条件下的破坏规律,分析了工作面涌水机理,为以后工作面防治水提供理论依据,对于革新采煤工艺有很重要的实用价值。A coal mine 7199 working face in the process of mining, roof fissure zone conduction of roof sandstone water and water stone box set of floor sandstone, due to high water pour water for a long time, several mining face threatening. In order to achieve the 7199 working face under the condition of high pressure water inrush safety mining, through the water quality test, observed hydrologic observation, analysis, to determine water source and water law; Characteristics and water based on the analysis of working face water inrush during working face roof weighting rule were analyzed, find out the relationship between roof pressure and water; Use of rock under the condition of the periodic damage rule, analyzes the mechanism of working face water gushing, provide theoretical basis for future prevention and control of working face water, coal mining technology for innovation has very important practical value.
