会泽铅锌矿微震监测系统的构建及其应用

深井矿山开采过程中,地压活动频发。为有效掌控井下各类生产等诱发的地压活动时空分布情况,为研究岩体破坏震源及其附属的辐射能、地震级别、震源半径等参数及其蕴含的矿山工程岩体破坏机理,在深井矿山构建微震监测系统极为必要。以会泽铅锌矿微震监测系统的构建为工程背景,本文主要介绍微震监测系统的构建过程以及系统建成初期的实验性应用：分别以局部区域短时间内的生产活动和长周期内时序性地压活动为研究分析对象,综合对微震监测系统构建之后的实际作用效果进行分析并相互验证。通过现场调查与监测系统的数据分析,表明：微震监测系统能够精准反映矿山现场的各开采开拓活动；对监测地压活动的实时变化状态十分有效且更有助于分析变化趋势。

CONSTRUCTION AND APPLICATIONOF MICROSEISMIC MONITORING SYSTEM IN HUIZE LEAD-ZINC MINE

During the mining process of deep mines, ground pressure activities occur frequently. In order to effectively understand the spatiotemporal distribution of ground pressure activities induced by various types of underground production and study the rock source damage source and its associated radiant energy, seismic level, source radius and other parameters and the implications of the mining engineering rock failure mechanism, it is extremely necessary to build a microseismic monitoring system in the mine. Taking the construction of the micro-seismic monitoring system of Huize lead-zinc mine as the engineering background, this paper mainly introduces the construction process of micro-seismic monitoring system and the experimental application in the early stage of the system construction: respectively, the production activities in a short time in a local area and the time series in a long period. The pressure activity is the research object, and the actual effect after the construction of the microseismic monitoring system is comprehensively analyzed and verified. Through the data analysis of the on-site investigation and monitoring system, it is shown that the microseismic monitoring system can accurately reflect the mining activities at the mine site; it is very effective in monitoring the real-time change state of the ground pressure activities and is more helpful to analyze the changing trend.
