摘要:

煤矿地质赋存及开采条件的差异性使得寻找统一的冲击地压发生机理及防治策略较为困难, 对冲击地压矿井进行合理分类, 将是支撑工程现场有效开展防冲工作的可行路径。以鄂尔多斯地区煤田为工程背景, 基于大量现场调研, 分析了煤田内部构造特征及其对冲击地压的影响, 认为鄂尔多斯地区的东胜煤田、桌子山煤田及上海庙煤田均面临不同程度的冲击风险。考虑冲击地压的发生机理、灾害位置、载荷(力源)、采掘环境等要素, 将典型冲击地压矿井划分为重力型、构造型、顶板型、煤柱型等4 种类型, 并对应提出了鄂尔多斯地区深部冲击地压矿井类型的划分方法,同时结合各类型冲击地压的形成机制, 明确了其对应的防治要点, 为具体防冲工作中设计针对性的措施提供了可靠手段支撑, 以此为依据的冲击地压防治工程实践效果良好。

Abstract:

The difference of coal mine geological occurrence and mining conditions makes it difficult to find a unified occurrence mechanism and prevention strategy for coal bump, and a reasonable classification of coal bump mines will be a feasible path to support the effective development of anti-coal bump work in the engineering site. Based on a large number of field investigations, this paper analyzes the structural characteristics of each coal field in Inner Mongolia and Shaanxi mining area and its influence on coal bumps. It is concluded that the Zhungeer coal field, Dongsheng coal field, Zuozishan coal field, Shanghaimiao coal field and Shanbei jurassic period coal field Inner Mongolia and Shaanxi mining area face a different degree of risk of rock burst. Considering the occurrence mechanism of coal bump, disaster location, load (force source), mining environment and other factors, typical coal bump mines are divided into gravity type, structural type, roof type and coal pillar type. The classification method of coal bump mine types in Inner Mongolia Shaanxi deep mining area is put forward. Combined with the formation mechanism of each type of rock burst, the corresponding prevention and control key points are clarified. clear the corresponding prevention and control points. This provides a reliable means to support the design of specific measures for the mine's anti-scour work, and the engineering practice of coal bump prevention based on it has achieved good results.
