摘　　要：为改善井下热环境,分析了目前的深井冷控系统,确定一种不仅能够满足大规模工业化制冷,而且有技术经济优势和推广前景的制冷方式。该系统通过气体的绝热膨胀冷却井下水源,代替制冰机等制造冷水以满足矿井制冷需要。通过分析所用压气量与制造冷水量的关系,建立了压气绝热膨胀后制造冷水的温度、质量与压气量间的数学关系式。分析并比较了压气冷水系统与地面集中式制冷降温系统的降温成本和效果,得出压气冷水系统优于其他制冷系统的结论。In order to improve the thermal environment of coal mine, the current cooling control systems of deep mine were analyzed, a new cooling control system of deep mine was proposed, meeting the requirement of large - scale industrialized cooling, with technical economy advantages and promotion prospects. Gas adiabatic expansion was applied to cool water, instead of ice machine, to meet the needs of mine cooling. By analyzing the relationship of compressed air flow and cooling water yield, a mathematical relationship was established, between the temperature and yield of cooling water and the compressed air flow amount. The effect and costs of the proposed system and ground centralized refrigeration cooling system were compared, and the proposed system was preferred.
