矿块结构要素
constructional element of ore block
k旧ngkuo{j一egou yaosu矿块结构要素(eonstruetional element of ore-block)按采矿方法要求矿块被划分成的分块或块段及其在其中的巷道和构筑物。矿块可被分为矿房、间柱、阶段间矿柱、分段、分层、分条等。矿房是矿块的酮室形待回采矿段及所占据的空间矿柱是矿块中支撑矿体围岩，使其处于稳定状态的矿段〔见图);顶柱、底柱和间柱分别是位于矿房之上、之下和侧面的矿柱。阶段间矿柱是指两个相邻阶段之间的矿柱，由上阶段底柱和下阶段顶柱构成。有的矿柱在fi1采完矿房后回采，有的则不回采。无必要时不在矿房周围留矿柱分段和分层是矿块沿高度方向被进一步划分出的待回采的水平矿段，常用中深孔爆破分段，浅眼爆破分层。分条是矿块沿水平方向进一步划分出的待回采的矿段。 矿块中的巷道是采准、切割巷道和切割回采后形成的空间。这些巷道中的构筑物和设备包括支架、格筛、装矿漏口、人工底柱以及充填体和其中的人行天井和溜井等。 〕八八八八八门八八八介八门卜八八八八门[ 夕耳二二爪二二了二二二二节写二二二二二弋士二咒二二p亡:二井二二二二二二二二二二夕c 习只户叹悦尸-二户口\亡口‘ 羹昼蒙一，遥家一‘药县遥 {舔而不焉豁种麟愚滁确淄盖 —一份下 留矿采矿法矿块结构要素 1运输平巷;2一人行天井;3一人行平巷;飞放扩巷道; 5一犷房;6一顶柱:7底柱;8一间柱 矿块结构是矿块结构要素的综合。 矿块结构参数是矿块结构要素尺寸，它对开采效果有重大影响。确定矿块结构参数时类比法起重要作用，但科学计算法的比重日益增大。
