恰如其分地评价钻孔的孔斜,对正确地指导施工及评价资料的可靠程度都具有一定意义。目前,孔斜质量评定是按1978年3月煤炭部颁发的《煤田勘探钻孔质量标准》(以下简称《标准》进行)。此标准按甲乙两个级别对不同深度的钻孔孔底斜度分别做了规定。我们在实际工作中对此评定方法感到有不足之处。对于斜孔资料的可靠程度,地质人员主要 Appropriately evaluating the hole inclination of the borehole is of some significance for correctly guiding the construction and evaluating the reliability of the data. At present, the slant hole quality assessment is based on the “coal prospecting drilling quality standard” (hereinafter referred to as “standard”) issued by the Ministry of Coal Industry in March 1978. This standard according to A and B two levels of different depths of the hole at the bottom of the hole made the provisions of the slope. We feel there is something wrong with this assessment method in practical work. For the reliability of inclined hole data, the main geological personnel
