| 摘 要： | 本文介绍了铜矿峪铜矿矿块崩落采矿法试验中矿块底部结构地压监测研究成果。在研究过程中应用ＪＸＨ－２型混凝土应变计对矿块崩落法混凝土底部结构的应力应变进行了系统的监测，不仅摸清了在拉底及崩落出矿过程中，出矿巷道的应力应变变化规律，以及出矿巷道在生产过程中的２个破坏危险期，而且为矿块崩落法巷道支护及地压控制提供了依据。

| Abstract: | In this paper the advances are reported in the ground pressure monitoring ofslusher drifts supporting system during block caving mining at Tongkuanggu Copper Mine.By systematic monitoring the stress-strain pattern of bottom drifts using JXH-2 concretestrain-wire gage, the stress-strain relation in slusher drifts was revealed, and it was foundthat there are two most dangerous periods of drift support during block caving mining,whichprovides a practical basis for ground control and monitoring in a block caving system. |
