摘要
针对传统大采高综采面回撤通道在工作面末采阶段易出现底鼓、冒顶、片帮甚至冲击地压等问题,为实现超大采高综采工作面设备的安全高效回撤,本文以金鸡滩煤矿12-2上117大采高工作面回撤通道设计为例,通过优化回撤通道设计,为更加安全有效回撤提供了有力保障,也为类似矿井提供了技术参考和指导。
In view of the problems of floor heave,roof fall,spalling and even ground pressure impact in the end mining stage of traditional large mining height fully mechanized mining face,in order to realize the safe and efficient withdrawal of equipment in fully mechanized mining face with super large mining height,in this paper,Jinjitan Coal Mine 12-2 on 117 large mining height working face design as an example,through the optimization of the withdrawal channel design,for more safe and effective withdrawal provides a strong guarantee,but also for similar mines to provide technical reference and guidance.
