以贵州某矿为研究对象,用混沌-分形理论对该矿裂隙规律进行分析研究。从能量的角度解释首先产生的是横向离层裂隙。从下层岩层到上层岩层,裂隙数量减少,两邻边呈锐角发育。最后对裂隙进行分形计算,运用数学拟合裂隙数与推进距离的关系得出纵截面岩体裂隙分形维数值在0~2变化,基于分形维数对煤与瓦斯突出机理进行分析,预测出当纵截面岩体裂隙分形维数无限趋近于2时,易产生煤与瓦斯突出。
Taking a mine in Guizhou as the research object, the chaos fractal theory of the mine is analyzed by chaos - fractal theory. From the energy point of view the first to produce a lateral fissure. From the lower strata to the upper strata, the number of fractures decreases and the two adjacent edges develop acutely. Finally fractal calculation of fissures, mathematical fits the relationship between the number of fissures and the propulsion distance obtained fracture fractal dimension of the longitudinal section of the rock changes in 0 ~ 2, based on the fractal dimension of coal and gas outburst mechanism analysis, predict when The fractal dimension of fractured rock mass in the longitudinal section approaches to 2 o’clock indefinitely, so coal and gas outburst are easy to occur.
