• Factors determining the application of underground metal mining methods are:

• Shape, size, regularity and dip of the orebody, distribution of ore, strength and physical character of the ore and wall rocks or overlying material, relation of deposit to surface and to other orebodies or to existing shafts on the same property ;

• 决定地下金属采矿法应用的因素是:矿体的形状、大小、规律性和倾角,矿石分布,矿石及两帮与上覆岩层的强度和物理特性,矿体与地表以及与其它矿体的联系或与同一区域内现存井筒的联系;

• availability, character and cost of timber and material for filling These factors are interdependent and of varying importance, the method chosen must be safe and give maximum extraction.

• According to the particularity of the contradiction between mining and ground pressure possessed by mining methods, in general they may be grouped as follows: open stope, shrinkage stope, filled stope and caving methods.

• 根据采矿方法所据有的开采和地压管理之间的矛盾特点,一般来说,采矿方法可分类如下:空场法,留矿法,充填法和崩落法。

• An open stope is stope in which no timber or filling is used to support walls, a finished stope is an open caving, the walls are supported by pillars of ore.

• 空场法就是在采场内没有应用支柱或充填支撑围岩,采空区处于敞空状态任其崩落,围岩由矿柱支撑。

Page 16: Lesson Four

16

• Sublevel stoping is an open stope method, it is a relatively low cost method. It does not permit very effective sorting and is therefore applied where values are fairly uniform. This method may not be advantageous in very hard ore due to the high cost of driving sublevel, it is best adapted to steep dips, but has been successful on flat dips too.

• 分段采矿法是空场法的一种,它相对来说是一种低成本的采矿法,其不能进行有效的选别采矿,因此应用于开采价值相同的矿体。此方法应用于坚硬的矿石中,由于掘进分段平巷费用高,其可能是不利的,此方法比较适合于急倾斜矿体开采,但是也成功地应用于微倾斜矿体。

• Shrinkage stopes are overhand stopes where part of the broken ore remains in the stope as a means of support and affords a working platform until the stope is completed.

• 留矿法是上向梯段工作面,部分的爆落矿石留在矿房内,既作为一种支护方式,又提供了一个工作平台,直到这个矿房回采结束。

• In mining large orebodies it can be applied where the orebody itself is self-sustaining across its width and where the wall are sufficiently firm to stand without support over a considerable length along the strike of the vein.

• 在开采厚大矿体时,留矿法可应用于矿体自身沿厚度方向足够稳固以及围岩充分稳固不垮落,沿着矿脉走向横跨较长距离而不需支护的位置。 ( 可以这样理解:即在开采厚矿体时留矿法矿块垂直于矿体走向方向布置,矿块长度为矿体厚度,然后再沿矿体走向方向确定矿块宽度 )

• Caving methods, strictly speaking, are those in which the ore is first undercut and then broken down by its own weight or by the weight of overlying rock, or by a combination of both.

• 严格地说 , 崩落采矿法是一类首先在矿体中底部掏槽,然后矿石依靠自身重力崩落或者在上覆岩层的压力作用下崩落或者在上述二者的联合作用崩落下来的采矿方法。(实际这里定义的是自然崩落法)

• But as a result of custom operation involving caving of the material overlying an orebody, as a systematic and essential part of the work, are also classed as caving methods. Though all the ore is broken by drilling and blasting, three distinct methods, sublevel caving, block-caving and top-slicing result from this classification.

• 但是由于习惯性做法,包括崩落矿体的上覆岩层,这是崩落采矿法系统中必不可少的一部分工作,也被看作崩落法。虽然全部矿体爆落通过钻眼和爆破,但三种截然不同的方法,分段崩落法,分块崩落法,下向分层崩落法产生于这种分类法。
