一、前言北布罗肯山(North Broken Hill)矿的第二号竖井地区生产已停止,全部采矿工作转移到第三号竖井地区,所以必须在3~#井附近新建一套充填系统,以最后完成这一变动。过去3~#井地区的充填工作是依靠2~#井地区的充填系统供给充填料的,干的尾砂通过皮带运输机运到15中段(1850呎)的搅拌站。加拿大的Kerr Anderson矿曾试验过并证实了湿的尾砂能够储存并再利用重新制浆供充 I. INTRODUCTION Production of shaft No. 2 in the North Broken Hill mine has been discontinued and all mining operations have been relocated to shaft 3. Therefore, a new filling system must be built near wells No. 3 to The final completion of this change. In the past, the filling work in the area of ​​well 3 ~ # was based on the filling system in the area of ​​2 ~ # wells. The dry tailings were transported by belt conveyor to the middle of the 1550-ft mixing plant. The Kerr Anderson mine in Canada has tested and confirmed that wet tailings can be stored and repulped for repulping
