根据国内外充填法矿山大量开采实践经验分析看来,我国冶金、燃化和国防系统水砂充填法矿山,随着开采深度的增大,今后在水砂输送作业中,若充填管路及其系统设计欠合理,难免要不同程度地出现充填管的崩裂问题。管道崩裂,不但全线输砂终断,打破正常的充采计划,影响全矿生产,而且铁屑砂碎四处飞溅,可能击刺敷管巷道内的操作和过往人员,危及人身安全。这是深采矿山的潜在问题,须有一定的重视。 According to the practice of large-scale mines mining at home and abroad, it seems that China’s metallurgy, combustion and defense system of water sand filling method with the mining depth increases in the future operation of the water sand, if the filling pipe and its System design is not reasonable, it is inevitable to varying degrees, filling pipe cracking problems. Pipeline cracking, not only the entire line of the final cut off the sand, breaking the normal charge of mining plan, affecting the whole mine production, and scrap iron sand splashing around, may stab the operation and past personnel in the pipeline tunnel, endangering personal safety. This is a potential problem for deep mining and requires some attention.
