For topslicing caving in a certain mine, the raise sites which were often driven formerly in the orebody or its hanging wall have showed a lot of defects. Based on practical experiences and analysis, the raise sites in footwall are suggested and discussed in this paper.

某矿采用分层崩落法回采,采准天井以往都是打在矿体内或上盘围岩中,存在的缺点较多。本文对把采准天井打在下盘的布置方式进行了探讨。

Generally top slicing is a mining method of high cost, low productivity, and large consumption of timber as compared with other methods for mining metalliferous ore bodies. In this paper, the necessity and suitability of adopting top slicing technique and its improvements are mainly stated in light of the actual conditions in No. 715 uranium mine with irregular ore bodies of high grade. The said mine has been competitively developing as a fruitful result of better economic effects, improvement of operational...

Generally top slicing is a mining method of high cost, low productivity, and large consumption of timber as compared with other methods for mining metalliferous ore bodies. In this paper, the necessity and suitability of adopting top slicing technique and its improvements are mainly stated in light of the actual conditions in No. 715 uranium mine with irregular ore bodies of high grade. The said mine has been competitively developing as a fruitful result of better economic effects, improvement of operational safety, less hard labour, low ore depletion and higher productivity of ore owing to the improvements of top slicing mining technique.

对于金属矿的开采,一般认为分层崩落法与其他采矿法相比,是一种成本高、产量低、木材消耗量大的采矿方法。根据七一五铀矿的开采实况,本文论述采用分层崩落法的适应性和必要性,并着重叙述该方法所存在的主要问题及解决的措施。从而使分层崩落法的主要工艺有所改进。

In order to solve the problem of the mining method in Fuxu Gold Mine, a method, the descending slicing method with armoured concrete protecting slabs has been designed, This method is found to be free from the disadvantage existing in the slicing or caving method, but has the advantage of natural and artificial support mining method . It is applieable to gold ( argentum ) vein deposits with a thickness ranging from 1-4 metres, an inclination from 50-90degrees and medium stability of ore and surrounding rock...
