通过对东滩矿六采区范围内的不良地质构造分类及对古构造运动的研究,得知区内构造是燕山运动和喜山运动共同作用的结果,根据矿区构造特征阐明了古构造应力场的性质。结合矿区地应力实测结果,给出2种对区内岩体是否会继续沿着断裂面继续滑动的判别方法,并判定采区处于稳定的地应力场,不会发生构造运动。当今水平应力的方向与大小以及岩体所处的深度直接影响了裂隙的后续发育状态并影响了岩层的导水性,深度应该作为裂隙评价的重要因素之一。
Based on the study on the classification of the unfavorable geological structure in the six mining areas of Dongtan mine and the study on Paleo-tectonic movement, it is concluded that the intracontinental tectonics is the result of the Yanshan movement and the Himalayan movement. Based on the tectonic features of the mining area, the paleotectonic stress field The nature of Based on the measured results of the in-situ stress in the mining area, two methods are provided to determine whether the rock mass in the area will continue to slide along the fracture surface. It is concluded that the mining area is in a stable geostress field and no tectonic movement will occur. The direction and size of the horizontal stress and the depth of the rock directly affect the subsequent development of the fractures and affect the conductivity of the rock. Depth should be one of the important factors in the evaluation of fractures.
