小煤柱工作面防治水优化设计

The optimizing design of the water control for small coal pillar face

14203工作面为麻家梁矿井首个小煤柱工作面,面临两侧采空区积水、顶板K5砂岩裂隙水水害威胁,本次根据该工作面两顺槽巷道的防治水特点,科学合理地对该小煤柱工作面的探放水设计进行优化并严格执行,确保在顺槽巷道掘进过程中安全通过,避免掘进工作面的突水情况的发生,为以后的工作面安全顺利回采创造可靠便利条件。

14203 face for Majialiang mine is first small coal pillar face, that faces both sides of goaf water, roof K5 sandstone fissure water hazards, this time according to the two face roadway water control characteristics, scientific and rational way of the water control for small coal pillar face was optimized and strictly the execution, to ensure the safety in the roadway excavation process, avoid driving face water inrush occurs, to create convenient conditions and reliable safety in face mining successfully for the future.
