摘要:

地表沉降是严重威胁矿山安全开采的主要因素之一,同时也是影响地表生态环境的重大问题之一。阔个沙也金矿矿体埋深极浅,采矿活动对地表影响不可忽视,以该矿山地表沉降为研究对象,基于GPS测量技术对矿山开采地表沉降特征和变形规律开展了监测分析,得到了不同监测阶段的地表沉降和水平移动曲线。沉降量最大的监测点是GC1,沉降量为-9.2 mm。工作面在推进的过程中形成了GC1和GC8 2个监测点位置的沉降区,GC1位置的漏斗相对较大,沉陷范围超过9 mm。不同监测点的x方向位移均呈现波动变化规律。监测结果为矿区变形规律研究提供了重要参考。

Abstract:

Ground subsidence is one of the main factors that seriously threaten the safe mining of mines,and it is also one of the major issues affecting the ground ecological environment.The ore body of the Kuogeshaye Gold Mine is extremely shallow and the ground subsidence induced by mining activity should be considered.In this paper,the subsidence of the mining area was taken as the research object.Based on the GPS measurement technology,the monitoring and analysis of the ground subsidence characteristics and deformation law of the mining area were carried out,achieving the ground subsidence and horizontal movement curves in different monitoring phases.The spot monitored showing the maximum subsidence degree is GC1 with subsidence of -9.2 mm.In the advance of workface,2 subsidence areas came into form at GC1 and GC8 and the chute at GC1 is relatively bigger with subsidence range exceeding 9 mm.The x-direction displacement at different monitoring spots all takes fluctuation variation rules.The monitoring results could provide an important reference for the study of the deformation of the mining area.
