| 摘 要： | 为了防治急斜煤层浅部综放开采出现的矿震灾害及深刻理解其机理,采用物理相似模拟实验进行了研究。研究结果表明,急斜煤层浅部矿震机理为单个煤柱失效后,进而引起采场煤柱连锁失稳,最终导致巨厚覆岩大面积垮落,产生矿震,其本质是空间结构失稳造成,由此提出"空间结构破坏型矿震"观点;结合生产实际,提出控制此类矿震的关键在于控制综放段上覆浮矸厚度,留设足够厚度的隔离煤柱和提前预爆破顶板的防治措施。 |
| 关 键 词： | 矿震 空间结构 综放 房柱式开采 |

| Abstract: | In this study,a physical simulation experiment was conducted to investigate the mine-induced earthquake phenomenon. The purpose of this study is to understand the mechanism of mine-induced earthquakes and prevent the disaster of mine-induced earthquakes in steep coal seam. The mechanism of the mine-induced earthquake was concluded that if a single coal pillar is disabled,all coal pillars will be soon disabled,and then eventually huge thick overlying rock will collapse and cause the earthquake. The nature of... |
| Keywords: | mine-induced earthquake space frame long-wall full mechanized top caving room and pillar mining |
