摘要
风阻是影响井下通风的重要因素.风阻越大,通风过程中风流量的损失越大,严重影响了矿井的通风效果,增加了矿井通风的电能消耗.因此,在巷道设计中,需要充分考虑风阻的问题,通过减少巷道长度、合理设计巷道断面等措施降低风阻.分析矿井阻力产生的原因,提出了降低矿井通风阻力的相关技术措施.
Abstract
Wind resistance is an important factor affecting underground ventilation.The greater the wind resistance,the greater the loss of the flow during the ventilation process,which seriously affects the ventilation effect of the mine and increases the power consumption of the mine ventilation.Therefore,in the design of roadway,it is necessary to fully consider the problem of wind resistance,and reduce wind resistance through reducing the length of roadway,reasonable design of roadway section and other measures.The causes of mine resistance were analyzed,and relevant technical measures to reduce mine ventilation resistance were put forward.
