  • 摘要

    为进一步提高微震监测系统定位精度,在传统微震监测技术基础上,提出一种新型自震式微震监测技术,通过自主研发自激震源,实现自动变频震动,实时计算煤岩体中纵波传播速度,优化微震系统参数,最终实现高精度、高可靠性监测微震事件。依托该技术自主研发的KJ768自震式微震监测系统已先后在跃进煤矿、石圪台煤矿、龟兹煤矿等多个现场进行了实际应用,结果表明:自震式微震监测技术在煤矿动压防治领域具有监测形式多样、监测精度高等特点,能够有效解决冲击地压灾害预警、浅埋煤层强动载矿压预警等问题。

  • Abstract
    in order to futher improve the postioning acuracy of the micro seisnic monitoring system,pased on the conventional micro seismic montoring technology a naw iniatve microsesmic montorin fechmology was provided. With a elf reseached and developed excited seisimic source, an automat c frequency converted seismic could be realized and the longtudinal wave propagatio speed in the coal and rock mass could be timely calculated. 7he paramnetersof the micro seismic systemcould be optimized and fnally the high accuracy and high relability monitoring could be realized for a micro seisnic acdent The selfresearched and developed KJ768initiatve micro seismic monitoring systen with the technology were appied to the actual appications in Yuejin Mine,Shigeal Mline,aiuc iMline and other several stes.The resulis showed that the intiative micr se smic monitoring technology would have the muti ype montoring high montoring accuracy and oter feaures in the mine dynamic pressure prevention and control area and could efe ctively soie the early waning of the mine strata rssure bunmp disaste;eary warming of the mine powerudynamic pressure from the shallow depth seam and other several problems.
