摘 要:结合郑煤集团公司米村煤矿的地质采矿条件,进行了水库坝体下放顶煤协调开采设计,并通过理论计算分析得出了水库坝体下放顶煤协调开采的导水裂缝带高度,研究了水库坝体下放顶煤开采的安全性。对水库坝体进行了灌浆加固,以增强坝体的稳定性和防渗能力。上述措施不仅确保了水库堤坝下放顶煤的安全高效开采,而且实现了水库坝体的安全运行。Combined with concrete geological and mining conditions of Micun Coal Mine in Zhengzhou Mining Group Co.,Ltd.,design on harmonic mining of top coal caving under reservoir dam was made,the height of water flowing fractured zone by top coal harmonic mining under reservoir dam had been get by the theoretical analysis and calculation,the security by top coal harmonic mining under reservoir dam had been studied.Grouting reinforcement technique was applied on reservoir dam to enhance the stability and anti-seepage ability of dam.The application of above measurements not only ensured the safety and efficiency of top coal caving under reservoir dam,but also realized the safe operation of reservoir dam.
