【摘要】介绍了在煤矿井下采用微地震定位监测技术监测岩体破裂的原理和开发研制的两种检波器及其安装方法。“液压安装法”适用于钻孔深度在50m以内的中硬及硬岩层,且检波器可以回收复用；“药包安装法”适用于软弱的岩层和深度50～100m的钻孔。该监测技术在现场得到试验验证并开始在工程中加以应用。更多还原

【Abstract】 Two kinds of geophones and their installing techniques used in microseismic monitoring underground coal mines were introduced. The method of installation with hydraulic expander can be used in middle hard and hard strata while the depth of drilling holes should be less than 50 m and geophones can be recycled. The method of installation with cement pouch can be used in soft strata and the depth of drilling holes can reach 50—100m. These geophones and their installing techniques were investigated by field tests and have successfully applied in underground coal mines.更多还原
