昆阳磷矿%露天采场%采区台阶高度
昆暘燐礦%露天採場%採區檯階高度

Kunyang Phosphate Mine%open-pit mining%bench height in working areas
台阶高度是采场要素中的一个重要参数，台阶高度确定的合理与否，直接影响设备的生产效率和采剥成本。随着矿山规模的增大，昆阳磷矿引进大型穿孔及铲装设备，高台阶采剥工艺将成为昆阳磷矿发展的必然趋势。根据昆阳磷矿5、6采区矿岩性质、爆破方式和穿孔及铲装设备的技术参数，采用计算法和类比法对5、6采区的台阶高度进行选取。得出昆阳磷矿5、6采区的台阶高度为15 m。
檯階高度是採場要素中的一箇重要參數，檯階高度確定的閤理與否，直接影響設備的生產效率和採剝成本。隨著礦山規模的增大，昆暘燐礦引進大型穿孔及鏟裝設備，高檯階採剝工藝將成為昆暘燐礦髮展的必然趨勢。根據昆暘燐礦5、6採區礦巖性質、爆破方式和穿孔及鏟裝設備的技術參數，採用計算法和類比法對5、6採區的檯階高度進行選取。得齣昆暘燐礦5、6採區的檯階高度為15 m。

Bench height is one of the most important parameters in key elements of mining areaS , and whether its determination is reasonable or not , directly impacts production efficiency of equipment and stripping cost .With the increase of mining scale and introduction of large -size perforation and shovel loading equipment , the high bench stripping technology will become the inevitable trend of Kunyang Phosphate Mine ’ s development .Accord-ing to ore properties in V and VI working areas , blasting mode and technical parameters of perforation and shovel loading equipment , selection for bench height of V and VI working areas was carried out by using methods of cal-culation and analogy in result that bench height of V and VI working areas in Kunyang Phosphate Mine was deter -mined as 15 meter.
