摘要/Abstract

摘要：

矿井高温问题已严重制约了矿井安全生产，影响了矿井经济效益，同时对井下作业人员的健康和安全也带来了极大的危害。高压气体作为井下的一种常用动力，具有膨胀吸热的特性，因此可以用于深井降温。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。

Abstract:

Mine high temperature problem has seriously restricted the coal mine safety in production, affected the economic benefits of mine. At the same time, the health and safe of underground workers has also brought great harm. Compressed air is often used for heat absorption while it is expanded into its surroundings. Just for its property, it is widely taken as an effective means to improve the underground deep—well ventilation. The current control systems of deep—well cold is analyzed, a new kind of deep cold control system was put forward. Gas adiabatic expansion is used to cool water, instead of ice machine, to meet the needs of the mine cooling. By analyzing the relationship of compressed gas and the manufacturing of cold water, a quantitative relationship between manufacturing cold water temperature, quality and quality of compressed air. The effect and costs of compressed air cold water system and ground centralized refrigeration cooling system are compared, compressed air cold water system is better.

Key words: Deep-well mine, Compressed air, Cold system, High temperature
