摘要
结合蜀河兴煤矿+710 m水平断层带煤层走向预测的工程实例,在已揭露煤巷内选取煤层底板测点,连接高程相当的测点,取其走向平均值作为预测走向值,再用其他测点验证。该方法仅施工1个探煤钻孔探明煤层走向,预测结果准确。
Takes the prediction of coal seam strike at +710 m level fault zone in Shuhexing coal mine as an engineering example, the measuring points in exposing seam of roadway floor are selected,connecting the same elevation measuring points and taking average values of coal seam strike as predictive value, then other measuring points are used to verify. This method only uses a coal seam drilling for construction and to prove the coal seam strike, the prediction results are accurate.
