摘 要: 矿山开采中涌水突水涌沙淹井实验研究都需进行固液耦合相似材料实验,但长期来由于没有寻找到合适的相似材料,井工采矿固液耦合实验一直没有突破性的进展。以陕北工程地质资料基础,通过固液耦合实验模拟了多个开采带对防水安全岩柱保护层及煤柱的稳定性的影响,确定了榆神府矿区在保护水的条件下的最大安全推进距离,提高了煤的采出率;为防治陕北矿区土地荒漠化,提出了不同工程地质条件下的保水采煤方案。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大意义。
关 键 词: 采矿工程;陕北矿区;土地荒漠化;耦合实验;保水采煤

Abstract: Studying flash flood, sand gushing and mine flooding during mining is in need of taking solid-liquid coupling simulation material experiments. The great progresse has not been made in solid-liquid coupling experiment for the underground mining because the suitable coupling materials have not been found in long-term. Based on the study the engineering geological conditions and solid-liquid coupling experiment, analyzed the Yushenfu Mine Areas’ desertification, soil and water erosion, water environment which whether be affected by the coal mining. Through the coal mining and environmental protections has analyzed the control problem of rock stratum of this area, and has put forward the scheme realizing water resources preservation during mining under the different engineering geology conditions. The obtained results are of great meaning to guide directly to the designing planning reasonable exploitation of the coalfield and environmental protections.
Key words: mining engineering; the Shaanxi Province northern mining area; the land desolate and boundlessization; solid-liquid coupling experiment; water resources preservation during mining
