泰山隆安煤业地质灾害易发分区及防治措施研究

Geological Disaster-prone Zoning and Prevention Measures of Taishan Long’an Coal Industry

为保障煤矿安全生产,以泰山隆安煤业为研究对象,开展全区野外地质灾害(隐患)调查,分析了全区地质灾害(隐患)的类型、发育特征及成因特征;基于地质灾害综合危险性指数法与定性、定量综合分析法,对研究区进行了地质灾害易发程度评价与易发分区。研究结果表明,全区共发育有直接威胁人类生命财产安全的地质灾害(隐患)点59处,主要类型为地面塌陷、滑坡、地裂缝、崩塌与不稳定斜坡,发育规模以小-中型为主,主要为采矿活动引发,同时切坡修路筑房、工业广场建设及特殊的地形地貌为灾害发育提供了基本条件;全区共分为高-中-低易发区3个大区、5个亚区,其中研究区西部及中东部各类地质灾害发育,是全区地质灾害重点防御区。此外,针对区内重点灾害(隐患)点,从技术层面提出了针对性的工程防治措施。研究结果可为我国类似矿区的地质灾害研究与科学防治提供参考。

In order to ensure the safe production of coal mines, taking Taishan Long’an Coal Industry as the research object, the investigation into geological hazards with hidden danger in the whole region was carried out. It analyzed the types, development characteristics, and causes of the geological hazards and the hazard susceptibility evaluation and zoning of the study area by the comprehensive risk index method and qualitative and quantitative comprehensive analysis method. The research results show that there are 59 geological hazards with hidden danger directly threatening the safety of human life and property in the whole region, including ground subsidence, landslide, ground fissure, collapse, and unstable slope. The hazard development, mainly caused by mining, is mainly small-and medium-sized. At the same time, cutting slope to build roads and houses, construction of industrial square, and special topographical conditions provided basic conditions for the hazard development. The whole region could be divided into 3 major regions and 5 sub-regions in terms of the susceptibility. Research on the various geological hazard development in the western area and central eastern area is the focus of disaster prevention. In addition, in view of the key hazards with hidden danger, targeted engineering measures were put forward technically. The results could provide a reference for the research and scientific prevention of the geological hazards in similar mines in China.
