摘要
本文通过实验室模拟放矿和现场放矿,试验研究了不同含水率、不同压实度条件下粉矿的放矿规律和特点.从而提出了“先上盘后下盘”、“先粉后块”、“先优先出矿口出矿后退采出矿”的放矿顺序,使试验矿块取得了较好的损失贫化指标。
This paper presents the drawing ore law and characteristics on the conditions of various water content and compression rate by modelling drawing ore in laboratory and production drawing ore on site There by,the drawing ore sequences of 'top wall at first and lower wall afterward', 'drawing ore from drawing hole at first and retreating drawing ore afterward'and 'drawing powder ore at first and drawing lump ore afterward'is put forward. Test results are indicated that the preferable indexes of ore loss and dilution in the stope are obtained.
