矿床开采技术条件矿床开采技术条件technical condition of miningkuongehL心ng ko一eo一J一shut一oojlon矿床开采技术条件(teehnieal eondition ofmining)指对矿床开拓、采矿方法、采矿工艺的选择和技术决策有影响的矿床赋存条件和矿岩性质。矿床开采技术条件主要有矿床的形状、倾角和厚度.矿岩坚固性(见岩石坚固性)、稳固性、粘结性、氧化性、自燃性和松散性等。矿床形状可分为:(l)层状矿床多为沉积或沉积变质矿床。规模较大，赋存条件稳定，有用矿物组分和含量较均匀。(2)脉状矿床多为热液和气化裂隙充填矿床。赋存条件不稳定，有用矿物组分和含量不均匀。(3)块状矿床多为充填和接触交代矿床。矿床大小不一，往往呈不规则的透镜状、巢状和株状产出，矿岩接触界限不明显。矿床倾角矿床倾角与采场运搬方式、地压控制和回采方式有关。矿床按倾角可分为:(l)水平及微倾斜矿床，倾角小于5。。(2)缓倾斜矿床，倾角为5’一300。(3)倾斜矿床，倾角为300~55。。(4)急倾斜矿床，倾角大于55“。矿床厚度矿床上、下盘间的垂直距离或水平距离。前者叫垂直厚度，后者叫水平厚度。对急倾斜矿床常用水平厚度。矿床厚度与矿块布置、回采方式、采矿方法、采场支护和地压控制有关。矿床按厚度分为:(1)极薄矿床，厚度小于。.sm。(2)薄矿床，厚度为。.8一4m。(3)中厚矿床，厚度为4一IOm。(4)厚矿床，厚度为10~4om。(5)极厚矿床，厚度大于4Om。矿岩稳固性已开采空间的矿岩允许暴露面积大小和暴露时间长短的性能。它对采矿方法的选择和地压控制有很大影响。矿岩按稳固性可分为:(l)极不稳固在掘进及采矿过程中，不允许有无支护的暴露面积。(2)不稳固允许无支护的暴露面积在50m2以内，长时间暴露则需支护。(3)中等稳固允许无支护的暴露面积为50一200m2。(4)稳固允许暴露面积为200一80om2。(s)极稳固允许暴露面积在80om2以上。粘结性采下矿石遇水或受压一段时间后而产生粘结的性质。对放矿、装车和采矿方法选择影响较大。氧化性采下的硫化矿石在水和空气的作用下发生氧化的性质。氧化后的矿石会降低选矿回收率。自燃性采下的高硫矿石(含硫18%一20%以上)在空气中氧化，并放出热量，一定时间后矿石温度升高引起自燃的性质。对采矿方法选择有其特殊的要求。松散性矿岩爆破破碎后，因空隙加大，其体积比原矿岩体积有所增大而松散的性质。破碎后的体积与原矿岩体积之比称为松散系数。其值一般为1.5一1.6，主要取决于破碎后矿岩的块度组成和形状。 (赵庆和)
