基于分形理论的煤矿突水量预测研究

Mine Water Inrush Prediction Research Based on Fractal Theory

断裂构造是煤层底板发生突水的控制因素,通过分析断裂构造与其他影响煤层底板突水因素之间的相互关系,利用分形理论研究断裂构造的发育程度,通过分维值的大小体现断裂构造的发育程度。以新安煤矿为例将分维值的大小与矿井最终突水量进行曲线拟合,研究分析二者之间的关系;通过分维值的大小划分研究区的断裂构造发育等级,为矿井的安全开采奠定理论基础。

Fragile structure is the controling factor of mine water inrush. Through the analysis of relationship between fragile structure and other factors of mine water inrush,doing the research of fragile structure development degree by fractal theory. And let the fractal dimension value reflect the development degree of fragile structure. Will carry on the curve fitting of fractal dimension value and the final mine water inrush based on Xin′ an mining area for example, and to analysis of the relationship between them; Dividing the developmental level of fragile structure in the study eara through the fractal dimension value.It can be the theoretical basis of safety mining in mine.
