摘要： 以山西焦煤霍州煤电集团吕梁山煤电有限公司方山店坪煤矿204 工作面为例，对无煤柱工作面W 型通风及其
沿空巷顶板控制进行了分析。从实际应用效果来看，W 型通风的应用避免了上隅角瓦斯积聚，提高了沿空巷通风稳定
性，保证了无煤柱工作面安全高效生产，取得了显著应用成效。

Abstract: Taking 204 working face of Dianping Coal Mine of Fangshan, Lvliangshan Coal Electricity Co., Ltd., Huozhou Coal
Electricity Group, Shanxi Coking Coal Group, this paper analyzed the W-type ventilation of the non-pillar working face and its
roof control along the goaf. It can be seen from the actual application effect that the application of W-type ventilation avoided the
gas accumulation in the upper corner, improved the ventilation stability along the goaf, ensured the safe and efficient production of
the non-pillar working face, and achieved remarkable application results.

Key words: non-pillar working face; W-type ventilation; roof control
