【摘要】：华恒矿采深较大,受底板灰岩突水威胁严重,针对断层控制突水的问题,利用分形理论及断层影响因子对煤层底板构造进行定量化研究;依据新汶矿区底板灰岩突水案例,利用散点图法和灰色关联分析法,对断裂构造与突水的相关性进行了分析,研究表明,断裂复杂程度与断层型底板灰岩突水危险性呈非线性正相关,断层影响因子是突水主控因素,断层分维值是次要因素;在此基础上,提出了断层型底板灰岩突水的断层控制指数,来判断井田内断层复杂程度、底板受构造破坏程度及突水危险性;通过分析计算,得出华恒矿断层控制指数临界值为0.70,并依此划分了突水危险区和安全区。
[Abstract]:The mining depth of Huaheng Mine is large and threatened seriously by the water inrush of floor limestone. Aiming at the problem of fault controlling water inrush, the structure of coal seam floor is quantitatively studied by using fractal theory and influence factors of fault, and according to the case of water inrush of floor limestone in Xinwen mining area, The correlation between fault structure and water inrush is analyzed by using scatter plot method and grey correlation analysis. The results show that the degree of fault complexity is nonlinear positive correlation with the risk of water inrush of limestone in fault type floor. The influence factor of fault is the main factor of water inrush, and the fractal dimension of fault is the secondary factor, on the basis of this, the fault control index of water inrush of limestone in fault floor is put forward to judge the complexity of fault in the mine field. Through analysis and calculation, the critical value of fault control index of Huaheng Mine is 0.70, according to which the dangerous area of water inrush and the safety zone are divided.
