冲沟下浅埋煤层采动巷道底鼓机理与防治技术

Mechanism of Floor Heave and Control Technology of Roadway Induced by Mining Beneath Gully Topography

根据寸草塔煤矿22107面回顺出现的底鼓现象,在详细分析地表形态、地质因素、采动因素及工作面布置等多种底鼓原因的基础上,提出了发生底鼓的机理具有二元特点的观点,并在分析巷道底板应力应变的基础上,结合国内现有防治底鼓的技术,采取了针对性的安全技术措施,达到了控制底鼓的目的。

According to the effect of floor heave in 22107 caving mining face air return way of Cuneaota coal mine ,based on the analysis of surface configuration, geological factor, mining factor and face arrangement that can lead to floor heave , proposed that the mechanism of floor heave has binary feature.Based on the analysis of strains and stresses on roadway, combined with current floor control technique, and used targeted safety technical methods to realize the goal of control floor heave.
