中深孔挤压崩矿连续采矿法的应用

针对矿山开采范围小、生产规模要求大,矿体产状突变,现有采准系统与矿体不吻合等生产技术问题,运用分段中深孔挤压崩矿技术,进行阶段连续后退式回采,较好地解决了生产中所存在的技术问题,实现了矿体安全、高效、低成本的开采。为矿山低品位资源的有效开发利用提供了有力的技术支持,并且在同类矿山中具有广阔推广应用前景。

Application of Continuous Mining Method with Squeez Caving of Medium-depth Hole

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.
