| 摘 要： | 阳泉三矿K8206综放面瓦斯超限严重,以相似理论为基础,设计制作了试验模型.在该模型上相对于工作面回风巷不同水平距离位置布置了4条内错尾巷,研究在高抽巷位置相对现场不变的条件下,不同位置组合的双尾巷治理工作面瓦斯的效果.试验结果表明,双尾巷能够显著地降低回风巷瓦斯的浓度,当双尾巷相对回风巷的水平距离分别为65 m和130 m时,治理工作面瓦斯效果最佳.

| Abstract: | The gas content of K8206 fully mechanized caving mining face in Yangquan No.3 Mine was highly over the gas limits.Base on the similar theory,an experiment model was designed and made.There were 4 alternate tailing gateways made along with the face return airway on different horizontal distance in the model.At the unchange condition of the relative site for the high level gas drainage gateway,the gas control results for the coal mining face with double tailing gateways in different location layout were resea... |
