一、校正孔深校正孔深，就是用丈量钻孔内全部钻具长度得出的实际孔深来校正报表中的记录孔深，并把它们之间的差值平衡到相应孔段的各个岩矿层中，使平差以后的分层厚度之和等于实际孔深。校正孔深是一项重要的钻探质量指标。为了准确地确定岩矿层的所在位置，钻孔的孔深记录必须与实际孔深相符。否则，会使岩矿层的埋藏深度、厚度和空间位置发生错误，构造形态被歪曲，特别是薄层的和稀有金属矿床更显得突出，从而降低地质资料的精度和质量，使矿床的开采设计和施工受到严重的影 First, the correction hole Deep hole correction, is to measure the actual hole depth measured by drilling all the holes to correct the statements in the record hole depth, and the balance between them to the corresponding hole in the rock In the mine, the sum of the stratified thicknesses after the adjustment is equal to the actual hole depth. Correcting hole depth is an important indicator of drilling quality. In order to accurately determine the location of rock and mine, borehole depth records must be consistent with the actual hole depth. Otherwise, the burial depth, thickness and spatial location of rock and mineral layers will be wrong, and the tectonic forms will be distorted, especially the thin and rare metal deposits will be more prominent, so as to reduce the accuracy and quality of geological data and make the mining design and Construction was severely affected
