保德煤矿梅花沟地质灾害危险性评估
|
摘要
保德煤矿地貌表现为黄土沟峁、丘陵地貌,梅花沟(黄河一级支流)与五盘区工作面呈35°夹角,经保德县城注入黄河,因此采空区塌陷对地表破坏大,易造成山体滑坡和泥石流,威胁流域内村庄和保德县城。如果对该地质条件没有一个清晰、明确的认识,就不可能真正实现煤矿的安全生产。因此,深入分析地表地质条件,开展地质灾害危险性探查,并制定相应的地质灾害治理措施,可为煤矿井下工作面设计提供可靠依据。
The landform of Baode Coal Mine is loess gully and hilly. Meihua gully and the working faces in fifth mining area are at an angle of 35 degrees,which is injected into the Yellow River through Baode County Town. Therefore,the collapse of goaf will destroy the surface greatly,easily cause landslides and debris flows,and threaten the safety of villages and Baode county towns in the basin. If we do not have a clear understanding of the geological conditions,it is impossible to truly achieve the safety production of coal mines. Therefore,by deeply analyzing the geological conditions and geological hazard risk and formulating the corresponding measures for geological hazards can provide a reliable basis for the design of coal mine faces.
