| 摘 要： | 新集二矿13-1煤为新生界松散层、推覆体下第一开采的特厚煤层,存在着与推覆体发育有关的隐伏构造裂隙水、离层裂隙水(气)、F02断层活化导水、冲击地压造成导水裂隙扩展等特殊的地质灾害问题。针对这些安全隐患,提出了留设防水煤柱、对离层空间充填注浆、选择合理的开采方案、加强采前探测等措施。

| Abstract: | No.13-1 coal of Xinji No.2 mine i s extra thick coal bed the first mining unde r Quaternary loose bed and nappe, there are some special problems of geological disast er related to development of nappe, such as hidden structural fracture water, fracture water (gas)in bed separation, conductive w ater caused by activation of Fo2 fault,pres sure bump. Aim at these hidden dangers of sa fety, submitted some harnessing measures, such as set safety pillar under water-bodie s, filled grouting in space of bed separati on, select reasonable mining scheme, enhan ce surveying before mining, and so on. |
