微地震技术在煤矿"两带"监测领域的研究与应用

综合微地震技术在山东兖州兴隆庄煤矿的应用情况，介绍了该技术的原理、特点、工作方法及应用效果。分析表明，微地震技术可以有效确定煤矿生产中断理解带与垮落带发育高度，同时，根据微地震事件的分布规律，可以解释采煤工作面周期来压、断裂带与垮落带边坡角、地下应力场的分布特征等与煤矿生产有关的重要理论问题，利用微地震技术两带监测具有周期短、费用低、成果可靠，并且可实现三维空间连续、动态监测等特点。

The research and application of microseismic technology in mine fractured and caving zones monitoring

The principle, characters, working methods and applied results of microseismic technology are presented combined with its application in Xinglongzhuang Colliery of Yanzhou Mine Ltd Corp, Shandong Province The gained information shows that the microseismic technology is effective in determination of the developed heights of the fractured and caving zones associated with coal mining Meanwhile some important theoretical issues related to coal mining, such as periodical pressure, slope angles of fractured and caving zones, the distributed characters of the ground stress field and etc can be explained according to the distributed regularity of the microseismic events The microseismic monitoring on the two zones posses not only short period, low cost, high reliability, but also realize continuous and dynamic monitoring in 3D space.
