OPEN STOPING
空场采矿法
An open stope is an underground cavity from which the initial ore has been mined. Caving of the opening is prevented (at least temporarily) by support from the unmined ore or waste left in the stope,in the form of pillars,and the stope walls (also called ribs or abutments). In addition to this primary may also be required using rockbolts , reinforcing rods, split pipes ,or shotcrete to stabilize the rock surface immediately adjacent to the opening. The secondary reinforcement procedure does not preclude the method classified as open stoping.
露天采场台阶是开采了地下矿石后形成的地下洞室。通过块矿或采场的支柱和(也称为肋或肩) 采场墙形式的废料的支持来(至少是暂时的) 预防放顶煤的开幕。除了这个,可能还需要使用锚杆,钢筋棒,分流管,或喷浆,以稳定紧邻开幕的岩石表面。二次加固过程不排除归类为开放式回采方法。
There are many forms of open-stope mining used to extract the initial material from mine .Having once established that the mineral and waste rock petent enough to use an open-stoping method ,and assuming that the reserve is not classified as gassy, the form which the method will take is primarily determined by the dip and thickness of the reserve .How these two factors affect the selection of the open-stope mining is discussed in a later chapter . At this point it will suffice to say that the classification of the open-stope mining system which follows is based on whether dry , broken material flows by gravity or whether it must be moved by non gravity methods where energy must be supplied to move the material.
这里有许多空场采矿法用于才出地下的矿石。一旦确立,矿物和废石足以胜任使用开放式回采方法,并假设储备不归类为高瓦斯,该方法将采取的形式主要取决于浸和储备的厚度。在后面一章,将讨论了这两个因素如何影响采场采矿法的选择。在这一点上就足以说的露天采场采矿系统的分类,根据是否干燥,破碎的物料通过重力或是否流动,它必须由非重力能源必须提供移动材料的方法提出。
Room-and Pillar-Mining
房柱采矿法
Room-and-pillar mining is an open-stoping method where mining progresses in a nearly horizontal or low angle direction by opening multiple stopes or rooms, leaving solid material to act as pillars to suppo
