坑探工程是地质普查勘探的重要手段之一.建国初期坑探发展较快,后来坑探工作量大幅度下降.由于坑探施工困难较多,导致地质工作者在认识和重视程度上不尽一致.有些同志主张不用或少用坑探工程.有些同志虽了解其重要作用,但在采用和实施坑探手段时,疑虑重重,难下决心.致使坑探受不到应有的重视,力量被削弱,技术水平难以提高,形成了落后的局面.随着今后地质事业的不断发展,坑探手段不但没有失去其作用,而且在某些场合能较好地发挥优势,因此坑探技术应当得到应有的重视和发展. Pit exploration engineering is one of the important methods for geological survey and exploration. Pit exploration has been developing rapidly in the early days of the founding of the country, and the amount of pit exploration work has dropped significantly. Due to the difficulties in pit exploration, geological workers are not always aware of and valued. It is unanimous. Some comrades advocate not using or using underground exploration projects. Although some comrades understand their important role, they have many doubts and ambitions in adopting and implementing the underground exploration methods. As a result, pit surveys cannot receive the attention they deserve. Being weakened, it is difficult to raise the level of technology and a backward situation has been formed. With the continuous development of geological undertakings in the future, not only has the underground exploration method not lost its role, but it has also been able to give full play to its advantages in certain situations. Therefore, the underground exploration technology should be obtained. Due attention and development.
