从孔庄煤矿井筒布置和矿井生产条件出发，先后总结、分析了片冰降温系统、热-电-乙二醇降温系统、井下低温水排热的井下集中降温系统（HEMS）和真空制冰降温系统。从集中降温方案效果、投资、降温系统运行稳定性、井筒输冷管路安装、矿井制冷水质、井下制冷排热等方面综合考虑，适合孔庄煤矿特点的集中降温途径只能是真空制冰降温方案，为矿井三期改扩建工程按期投产、验收创造了条件。同时，该降温工程的实施必将填补我国在矿井集中降温领域的一项技术空白，并在制冰技术、输冰管道、输冰工艺、压风冷却、井下融冰工艺、制冰节能技术上取得突破

According to the cross-section layout of Kongzhuang Coal Mine shaft and mine production conditions, the paper summarized and analyzed the systems of slice ice cooling, the thermo-power glycol cooling, HEMS underground centralized cooling, and vacuum ice cooling. From the effect, investment, cooling system operating stability, thermal transportation pipe installation, quality of water, discharge of heat underground, and other comprehensive consideration of the centralized cooling plan, the suitable way of cooling the mine is only the vacuum ice cooling scheme. Meanwhile, through implementation of the project, it will fill a centralized cooling technology gap in ice making technology, ice transportation pipes, ice transportation process, pressurized air cooling, underground ice melting technology, and energy-saving technology in ice making, which is a great breakthrough in our coal mines.
