为了适应地质普查勘探找矿工作的需要，我队曾于八一年举办了坑探采样短期训练班。参加坑探采样训练班学习的学员，有两个特点：一是文化程度高低相差悬殊；二是实践工作经历相差悬殊（有的从事坑探采样工作近二十年，而有的只有半年多）。这些同志，均未系统地学习过业务技术知识，故学习积极性较大。 In order to meet the needs of geological prospecting and prospecting work, our team held a short-term training program on pit exploration in August. There are two characteristics of trainees participating in training courses of pit exploration sampling: First, there is a great difference in educational level; second, there is a big gap between practical work experience (some are engaged in pit sampling work for nearly 20 years, while others are only more than six months) . These comrades did not systematically study the technical knowledge of the business, so they are more active in learning.
