新庄孜矿六八采区断裂复杂程度的分形评价

为了掌握井田断裂构造对矿区的控制情况,基于矿井地质构造的资料,采用分形几何学理论计算分维值,定量评价了淮南矿区新庄孜矿六八采区断裂构造的复杂程度,并根据复杂程度分为四类。六八采区分维值由北向南逐渐减小,形成了北部断层发育而南部断层不发育的总体构造格局,断裂构造复杂程度主要以Ⅱ～Ⅲ类为主。断裂构造复杂程度的评价为矿井安全高效生产提供了科学依据。

Fractal Evaluation of Fracture Complexity of No.6-8 Pannel in Xinzhuangzi Coal Mine

In order to know about distribution of field’s fracture structure in the pannel,based on the mine geological tectonics information,by using fractal geometry theory the fractal value was calculated,and fracture tectonics complexity of No.6-8 Pannel in Xinzhuangzi Coal Mine was quantitatively evaluated.Based on complexity,fracture tectonics were divided into four categories.In No.6-8 Pannel fractal value gradually decreases from the north to the south,in the northern part faults are developed and in the southern part faults not developed,and Ⅱ and Ⅲ categories of fracture dominate.Evaluation of complexity of the faults provides a scientific basis for safety and efficient production of the mine.
