摘要

It is of great significance to mine shaft coal pillar to ease the tension of coal mining and to reduce the backlog and waste of coal. Takai Iju mining is a new technology, from the current point of view, the technology is still relatively backward, still need to continue to study and practice.%开采井筒煤柱对缓和采掘接替紧张关系，减少煤炭的积压和浪费，具有非常重要的意义。立井井柱开采是一门新技术，从目前来看，这方面技术还较落后，尚需继续研究和实践。
