从理论上研究了独头煤巷掘进通风过程中风筒风量、风压特性,给出了风筒尾部风量与风机工作风量、风压计算公式。结合煤巷中各因素所需风量,提出了选择合适局部通风机方法,为掘进巷道通风提供思路。
The air volume and pressure characteristics of the ducts of a single coal roadway during tunneling and ventilation are theoretically studied. The formulas for calculating the air volume at the rear of the duct and the working air volume and pressure of the fan are given. Combining with the air volume required by each factor in coal roadway, a method of selecting suitable local ventilator is put forward to provide ideas for ventilating tunneling roadway.
