摘要/Abstract

摘要： 由于历史的原因，在铜坑矿三大矿体重叠的区域出现了一些四面环绕冒落体的盘区采场，此类采场开采技术难度大，存在诸多安全隐患。以92^#矿柱群Ⅱ采区作为试验采场，通过充分利用已有工程，并结合四周采空区冒落情况合理布置新工程，运用诱导式崩落法实现了Ⅱ采区的大规模高效安全回采，并及时消除了地压活动，为铜坑矿其他类似开采技术条件的采场提供了参考。

Abstract: Due to mining activities over the years，several panel stopes surrounded by falling rocks were formed in the overlapping area of three orebodies in Tongkeng Mine. There are many difficulties to recover this kind of ore-bodies，and potential safety hazards exist in the whole mining process. Taking mining area II in 92^# pillar group as a test case and with full use of the previous engineering，new projects are arranged in view of the falling conditions in surrounding mined-out area. Mining area II is extracted efficiently and safely with the induced caving method. Ground pressure activities are reduced in time. The research provides a reference for other stopes with similar mining conditions in Tongkeng Mine.

Key words: Pillar group, Large-scale mining, Induced caving
