| 中文摘要: |
| 以朱集矿工作面开采技术条件为背景，建立了工程地质模型，采用相似模拟实验，研究了工作面开采后，上覆岩层变形移动及裂隙分布演化特征，获得了采动岩层破断垮落及位移特征参数，以及与工作面推进度的相互作用关系，为留巷位置的合理确定、上行开采可行性等工程实践提供了科学依据。 |
| 英文摘要: |
| This paper establishes an engineering geological model in the technical conditions of Zhu Ji mine face. By Equivalent Material Simulation, it studies evolution characteristics of the overburden deformation moving and fracture distribution after the working surface has been mined,and obtains the characteristic parameters of mining strata breaking collapse and displacement as well as the relationship they have with the working surface advance The findings of this papper provide a scientific basis for determining the reasonable position of left lane and the ascending mining feasibility engineering practice. |
