![]() Based on the analyzing the spatial locations of the drill hole, the survey and evaluation of mineral resources can be directed specifically. Then, using the calculated results of the computer-related technology and software (including the GIS software) and the data processing principle, the paper has formed the trajectory simulation curve of the drill hole to achieve the purpose of the drill hole correction. Based on the analysis of reasons for drilling holes bending and discussion on the drill hole’s correction principle, firstly, the spatial locations in three-dimensional space and interrelations of each project point of the bending has been calculated and calibrated. ![]() Therefore, the accuracy of drill hole deviation correction is extremely vital to analyzing the geological bodies and ore beds precisely. Drilling is a widely-used exploration technique and method in the prediction and evaluation however, due to a variety of factors, such as, geology factors, exploration technique factors, equipment factors, human factors, the drill hole in the actual exploration process is to be displaced more or less compared with the drill hole originally designed. During the work of quantitative prediction and evaluation of mineral resources and scientific research, a variety of methods are needed to cooperate with each other to carry out scientific research and prospect and explore resources, such as, ore bodies and deposits.
