矿井井筒吊桶提升合理安全间隙的研究有结果凿井期间吊桶的安全间隙值，规程规定应随井深的增加而增加。当井筒深度大于５１００ｍ时，其安全间隙按规定不少于８００ｍｍ，因此常使施工深立井时难以配置大容量吊桶，在井径小的立井井筒尤为困难，从而制约了成井速度的提高... Mine shaft buckets to enhance the study of reasonable safety clearance bucket shaft safety results have occurred during the clearance value, rules and regulations should increase with the depth of the well. When the wellbore depth is more than 5100m, its safety clearance shall be no less than 800mm as stipulated, so it is often difficult to dispose large-capacity buckets when constructing deep vertical wells. It is especially difficult in wellbores with small well diameter, thus limiting the rate of well completion.
