红柳煤矿二号井井筒防冻设计方案研究

摘要

Combining with the engineering background of Hongliu Coal Mine No.2 shaft,the calculation parameters and equipment selection steps using air heating units were discussed,and five different shaft frost prevention schemes are analyzed and compared.By comparing the indoor temperature,air speed at the heapstead,influence on the indoor heating system and the equipment purchase cost,optimal scheme was determined.%结合红柳煤矿二号井的工程实例,论述了利用空气加热机组进行井筒防冻时各计算参数及选型步骤,并选用五种不同的井筒防冻方案进行分析.通过比较不同方案情况下井口房的室内温度、井口进风风速、对室内采暖系统的影响和设备购置费用等,确定了找到最佳的井筒防冻方案.
