Application of “coal-rock” spatial three-dimensional micro-seismic monitoring array for floor water hazard in the floor of Xinji No.2 Mine

摘要

摘要: 以新集矿区新集二矿为研究对象，借助矿区底板岩巷这一现场优势条件，通过试验对比分析了煤巷和底板岩巷不同组合方式下监测阵列效果，提出了基于底板岩巷“点面式”、“线线式”和“线面式”的3种空间立体“煤-岩”微震监测阵列，优化了现有微震监测阵列布置方式。研究表明：“煤-岩”空间立体微震监测方法从定位精度、监测范围、服务周期和经济成本方面取得了明显进步。

Abstract: Taking Xinji No.2 mine in Xinji Mining Area as the research object, with the help of the field advantage of the floor rock roadway in the mining area, the monitoring array effects under different combinations of coal roadway and floor rock roadway were compared and analyzed through field tests. Three spatial three-dimensional “coal-rock” micro-seismic monitoring arrays based on floor rock roadway are proposed, which are “point-surface”, “line-line” and “line-surface” respectively, and the existing micro-seismic monitoring array layout was optimized. The research shows that the “coal-rock” spatial three-dimensional micro-seismic monitoring method has made significant progress in terms of positioning accuracy, monitoring range, service cycle and economic cost.
