Abstract:

Aiming at such production technoloy issues as the scope of small mining, the large production scale, mutation ore occurrence, non-fitting mining barebone, squeez caving technology of medium-depth hole was applicated to solve issues above. In the mining method, safe,efficient, low-loss and low-dilution exploitation was made by means of continuous mining and back-style stage.Technology support is provided for effective development and utilization of low-grade ore and the method has broad application prospects.

Key words: Continuous mining, Squeez caving of medium-depth hole, Low-grade ore, Non-cemented filling
