综合分析法递进预测综采工作面冲刷带的特征

Progressive Prediction of Wash Zone Features on Fully-mechanized Working Face with Comprehensive Analysis Method

综合分析法采用物探、钻探、巷探、相邻巷道揭露、煤层厚度分析法、河流的侵蚀作用分析法、经验分析法等手段,递进分析预测冲刷带的范围、延展方向、岩性、宽度、深度、煤厚、煤质等特征;回采前应准确判断冲刷带对生产的影响。

Comprehensive analysis method （including geophysical prospecting, drilling exploration, roadway prospecting, adjacent roadway revelation, coal seam depth analysis, erosion analysis, and empirical analysis） was used in progressive prediction of the region, extending direction, lithology, width, depth, coal thickness, coal quality, and other features of the wash zone. Before caving, it is necessary to evaluate the influence of the wash zone on the mining.
