槽波透射勘探技术在寺河矿的精准应用

Accurate Application of Slot Wave Transmission Exploration Technology in Sihe Coal Mine

在井下综采工作面一侧巷道内激发槽波,另一侧巷道中接收通过采面透射的槽波。利用煤层与岩层的物理力学差异,分析在煤层中激发和接收到的槽波,以此来探查综采工作面中地质构造、煤体破碎区、应力集中区的位置,从而为后期探测地质构造参数、煤体破碎区注浆、应力集中区消突等工作的顺利进行提供基础数据,提高后期工程实施的针对性。

The slot wave was excited in one side of the roadway and received in the other side of the roadway.Based on the physical and mechanical differences between coal seam and rock stratum,this paper analyzed the slot wave excited and received in the coal seam,so as to explore the location of geological structure,coal body fracture area and stress concentration area in the fully mechanized mining face,so as to provide the basic data for the later exploration of geological structure parameters,grouting in the broken area of coal,and outburst relief in the stress concentration area,and improve the pertinence of the later project implementation.
