为合理开采地质及水文地质条件异常复杂区域边角煤,超化煤矿结合矿井生产技术水平和现有巷道布置情况,设计了开采复杂区域边角煤所必须的生产系统,经过分析、比较,使区域通风系统、浆液输送系统得到优化,并制定了安全高效的疏水降压方案,最终在复杂区域成功布置一个综采工作面。当矿井存在条件复杂边角煤时,应当科学设计,消除安全隐患,最大程度地回采煤炭资源。
In order to reasonably exploit the corner coal with abnormal geological and hydrogeological conditions and the production technology of the super-coal mine combined with the mine and the layout of the existing roadway, the production system necessary for mining the corner coal in the complex area was designed. After analysis and comparison, Regional ventilation system, slurry delivery system is optimized, and developed a safe and efficient hydrophobic step-down program, and ultimately successfully arranged in a complex area of a fully mechanized mining face. When the coal mine has complicated corner conditions, it should be scientifically designed to eliminate potential safety hazards and maximize the recovery of coal resources.
