对矿山地震研究进展、门头沟中尺度实验场概况和监测预测的实施方案等作了简要介绍．讨论了矿震与地震记录波形的差异，总结了１９８４～１９９５年ＭＬ＝１．０以上７．９万次矿震的震级－频次分布，并且还根据矿震的震源机制的主压应力分量ＰＨ和ＰＶ作为判据，对１２次较大矿震的应力背景进行了分析
The progress of mine earthquake research, the profile of Mentougou mesoscale experimental field and the implementation plan of monitoring and prediction are briefly introduced. This paper discusses the differences between mine and seismic records and summarizes the magnitude-frequency distribution of 79,000 mine shocks with ML = 1.0 and above from 1984 to 1995. Based on the principal compressive stress component PH And PV as a criterion, the stress background of 12 large earthquakes was analyzed
