摘　　要：介绍了现用的水砂充填采矿法特点及存在的问题:铺底、水砂充填、坑木支护等工艺环节多;充填体强度低;采场压力大;安全管理困难;生产效率低。如改用下向胶结充填采矿法能解决此问题,并介绍了下向胶结充填采矿工艺流程及要注意的技术经济等方面的问题。The article introduces the feature and problem of the currently adopted sand back fill process and compares it to cemented back fill process. The sand back fill process is featured with complicated procedures （sill mat, sand back fill, timber support, etc. ）, low strength, and high pressure in stope, low safety and efficiency. While the underhand cemented back fill process can solve all these problems. The article also introduces the process procedure of underhand cemented back fill process and the technical economy aspect to be noticed.
