介绍了井温测试、地面微地震法和动态导体充电法监测煤层水力压裂裂缝的基本原理，并通过采用上述3种方法对焦坪矿区煤层气井压裂裂缝进行监测，初步获取了煤层压裂裂缝的形态参数，通过分析发现：焦坪矿区煤层压裂空间展布显现出不等长垂直缝，压裂裂缝上下扩展明显，均穿越了煤层的顶底板，主裂缝延伸方位为北东向，建议生产井在长度方向上延主裂缝方向进行布置，井间距在400m左右为宜，在宽度方向上在140m左右为宜。

英文摘要：

The paper introduced a basic principle of the well temperature measurement and test, surface ground microseismic method and dynamic conductor charging method applied to monitor and measure the cracks developed with thehydraulic fracturing of the seam. With the above three methods applied to monitor and measure the cracks developed with thehydraulic fracturing of the coal bed methane wells in Jiaoping Mining Area, the crack shape parameters of the hydraulicfracturing in the seam were obtained preliminarily. The analysis showed that inequal length vertical cracks displayed andappeared in the fracturing space of the seam in Jiaoping Mining Area. The fractured cracks were expanded upward anddownward remarkably, were passed through the seam roof and floor and the expansion direction of the main crack were inNorth - East. The production wells should be arranged in the length direction along the main cracking direction, the spacebetween the wells would be about 400m suitably and the width direction of the wells would be about 140 suitably.
