摘要
选择在寸草塔煤矿22煤三盘区22301回风顺槽煤巷掘进工作面进行瓦斯涌出规律预测,该掘进工作面采用掘锚机全断面掘进,掘进断面积17.3 m2左右。为了使预测模型更加接近瓦斯涌出实际,通过瓦斯涌出有关参数的现场测定,对预测模型进行了修正,可指导矿井的通风设计和采掘部署,采取有针对性的防治煤巷掘进瓦斯灾害措施。
By actual measurement of gas emission law in№22301 return roadway heading face of Cuncaota Coal Mine,the relative parameters of gas emission was determined and the prediction model of gas emission was corrected. The research has a certain significance for guiding the mine ventilation design and taking the preventive measures of gas disaster in coal roadway tunneling face.
