京西矿震活动特征及其与天然地震关系初探

PRELIMINARY APPROACH TO THE RELATIONSHIP BETWEEN NATURAL EARTHQUAKES AND THE CHARACTERISTICS OF COAL MINE EARTHQUAKE ACTIVITIES IN THE WESTERN PART OF BEIJING

该文介绍了门头沟矿震的概况；对门头沟矿震与天然地震进行了相关分析，认为门头沟煤矿矿震活动可作为一种较好的监视首都圈中西部强震的中尺度监测手段；论证了门头沟煤矿矿震活动作为首都圈地应力变化监测哨的地质依据，并初步建立了矿震作为地震前兆的力学模型；提供了矿震预测天然地震的地质依据。

The authors of this paper outline the coal mine earthquakes occurring at the Mentougou coal mine; analyze the relationship between natural earthquakes and coal mine earthquaks occurring at the Mentougou coal mine, considering that coal mine earthquake activities in the coal mine can be taken as a relatively good medium-term means of monitoring strong earthquakes occurring in the central and western parts of the capital region; demonstrate the geological basis for taking coal mine earthquake activities in the Mentougou coal mine as a post of monitoring ground stress variation in the capital re- gion, having developed the mechanical model of coal mine earthquakes as earthquake precursors; pre- sent the geological basis for predicting natural earthquakes by means of coal mine earthquakes.
