摘　　要：赵固二矿风井筒穿过的冲积层厚度达到528.85 m,地质、水文地质条件复杂,冻结设计和施工难度较大。煤科总院北京建井所在总结赵固一矿、泉店矿冻结制冷设计、施工经验和教训的基础上,对赵固二矿的风井冻结制冷方案进行设计优化,达到了安全、合理、快速、经济的目的。The alluvium thickness of air shaft in Zhaogu No. 2 Coal Mine is up to 528.85 m. The geologic and hydrographic conditions are complex, so it is very difficult for freezing design and construction. Based on some design and construction experiences on Zhaogu No. 1 Coal Mine and Quandian Coal Mine, project design for air shaft freezing refrigeration of Zhaogu No. 2 Coal Mine is optimized by Beijing Construction Shaft Department of China Coal Science Research Institute. This design plan is safe, reasonable, quick and economical.
