摘要
本文根据苍村平硐开采技术条件及生产现状，对矿井开拓延伸通风方式方案进行了技术分析和经济比较，提出废弃现2号斜风井，在姜家沟开掘新斜风井形成新的一进一回并列式通风方式。对矿井未来的安全生产及经济效益将产生重要作用。
According to mining technical conditions and production station of Cangcun Drift development , the paper puts up technical analysis and economic comparison on the plan of ventilation ways in mining development exten- ding , and puts forward a new march -past ventilation with one intake airflow shaft and one return airflow shaft, and No2 inclined airflow shaft is closed. It will have great importance for safety production and economic profit in future.
