摘要
地下转露天开采时，矿山采空区处理是一件十分棘手而又相当重要的头等大事。依据伏萨尔架法基本原理，开发了高台阶处理采空区工艺，在河南某钼钨矿的应用取得了很好的效果。
When mining is transferred from underground to open pit operation, the elimination of mined - out areas becomes a troublesome but very important matter. Based on the fundamental principle of the Fusar Beam Method, a high bench approach is developed for elimination of mined - out areas, the successful application of which has yielded remarkable results in a molybdenum - tungsten mine in Henan Province.
