【摘要】 以陕北矿区工程地质资料为基础,通过大量试验筛选,得到石蜡适合作固液耦合实的胶凝剂,并做出试件物理力学参数随不同相似材料配比的变化规律,从而获得榆神府矿区各岩层相似实验配比。针对榆神府矿区沙基型覆岩及富水特点,进行了固液耦合水资源保护实验,得出了采用间歇式开采的合理推进距离。研究结果对指导该区煤炭资源合理开发、规划、设计和环境保护具有重要意义。更多还原

【Abstract】 Based on the study of the engineering geological conditions and solid-liquid coupling experiment , the paper analyzed the Yu- shen- fu Mining Area desertification,soil and water erosion, water environment which whether be affected by the coal mining. By the experiment of water protectian,the article put forward the rational advancing distance of intermission mining method. The obtained results are of great meaning to guide directly to the designing,planning,reasonable exploitation and environmental protections in the coal field.更多还原
