摘要:
基于覆岩空间结构理论,一面采空、两面采空边界条件下覆岩结构称为“O”型和“S”型,结合矿压知识及工程背景的特殊条件,将二者转换过程中覆岩结构定义为“O-S”型。在系统分析三种结构构成、运移规律和应力分布特征的基础上,对矿山动力事件进行分析与防治;现场侧向支承压力监测结果显示基于覆岩空间结构理论的结构构成及相关计算相似,现场顶板岩层离层监测结果显示基于覆岩空间结构理论的覆岩运移规律阐述可靠,工作面矿压特征监测结果显示基于覆岩空间结构理论的特厚煤层矿压特征分析与实际发生情况基本一致,研究可为类似条件下矿压特征分析与岩层控制提供一定借鉴。
Abstract:
Based on the overlying strata spatial structures theory, combining with the mine pressure knowledge, according to the boundary conditions in the actual mining process of extra-thick coal seam mining face, one side goaf, two sides goaf and the conversion process structure of overlying strata were defined as "O","S" and "O-S" letter type overlying strata spatial structures. On the basis of the systematic analysis on three kinds of structure formation, structure movement and stress distribution feature, the mine dynamic events were predicted and prevented. The field monitoring results of side abutment pressure showed that the structure based on the theory of overlying strata spatial structures theory was basically right. The roof separation monitoring results showed that the rules of overlying strata movement based on the overlying strata spatial structures theory were basically correct. The monitoring results based on pressure characteristics according to the characteristics of thick coal seam mining overlying strata spatial structure theory prediction were consistent with the actual situation of mine pressure field. The research provides certain reference for mine pressure feature prediction and strata control under similar conditions.
