炉渣－废石混合料水力充填试验

Experiment or Hydraulic Filling by Mixture Composed of Slag and Waste Rock

利用炉渣和废石制备充填料用于采空区充填在国外有很多的实践经验，而国内的应用较少．对某锑矿所开展的这方面的研究工作表明，利用炉渣和废石混合料水力充填采空区技术上可行、经济上合理，不但可以降低采矿成本，扩大充填料来源，而且可以做到废物利用。

There arc many practical experiences on hydraulic filling in mined-out area by slag and waste rock overseas. However the application of this filling method at home is only a few. Based on the test-study result of a certain antimony mine,showing that the hydraulic filling technique by slag-waste rock mixture is feasible,and economic rational,not only it is able to teduce mining cost,and to extend filling material resource,but it allow to utilize waste material.
