摘    要:提出了利用打钻过程测定煤体强度的方法,通过实验证明,打钻时的钻削功率值能够反映占削煤体的坚固性系数,二基本上呈线性关系。应用该方法在现场的测定结果符合实际情况,为在现场实测煤体强度提供了一种新的方法。

关 键 词:钻孔法  钻削功率  煤体强度  突出预测  瓦斯突出

Abstract:A method for determination of coal mass strength through boring is proposed. It is proved by the laboratory tests that while boring in coal seam the value of drilling power can reflect the solidity coefficient of coal mass, and there is linear relationship between the two parameters. The results of site measurement by using this method conform with the practical situation. The study provides a new approach for determination of coal mass strength on the spot.
Keywords:boring method  drilling power  coal mass strength  prediction of outburst
