摘要
榆神矿区是我国重要的产煤基地,由地下煤层开采而导致的地表塌陷和裂缝对这里的生态环境和地表建筑物造成了严重的破坏。研究煤层开采引起的地表裂缝的特点,对保护地表建筑物具有重要意义。小保当煤矿是榆神矿区的一个大型煤矿,具有榆神矿区煤矿的典型开采特点。通过对榆神矿区陕西小保当煤矿132201工作面进行地表移动观测,分析了该矿的裂缝发育特征。
Yushen mining area is an important coal production base in China.Surface collapse and cracks caused by underground coal mining cause serious damage to the ecological environment and surface buildings here.To study the characteristics of surface cracks caused by coal mining is of great significance to the protection of surface buildings.Xiaobaodang coal mine is a large scale coal mine in Yusen mining area,which has typical geological and mining characteristics of yusen coal mine.Based on the surface movement observation of 132201 working face of Shaanxi Xiaobadang coal mine in Yushen mining area,the author analyzes the development characteristics in the mine.
