Underhand cut-and-fill with cemented backfill is a high-recovery mining method, especially adoptably for those ore deposits which are rich in grade but unstable in ground conditions as the orebody and sur-rounding rocks are both concerned. However, its efficiency is rather low, its stope productivity also is quite limited and a considerable quantity of material needs to be used for supporting. By using high accesses which are staggeringly laid out between vertically adjacent suble-vels,its efficiency and stope...

Underhand cut-and-fill with cemented backfill is a high-recovery mining method, especially adoptably for those ore deposits which are rich in grade but unstable in ground conditions as the orebody and sur-rounding rocks are both concerned. However, its efficiency is rather low, its stope productivity also is quite limited and a considerable quantity of material needs to be used for supporting. By using high accesses which are staggeringly laid out between vertically adjacent suble-vels,its efficiency and stope productivity can be remarkably enhauced and its timber consumption to meet support requirement will be greatly reduced. In this paper, an introduction is presented about the stope layouts and mining techniques adopted in a series of field tests for this method at Lungsou mine, Jinchuan Nonferrous Metals Co. And a stability analysis for rib pillars made up of ore and cemented backfill during mining operation is also given.

下向胶结充填采矿法是一种回采率较高的方法,适合于高品位且矿体围岩均不稳固的矿床条件。然而这种方法的采矿工效低,采场生产能力小,且需消耗相当数量的支护材料。采用高进路,并使相邻分层的回采进路交错布置,可使其采矿工效及采场生产能力明显提高,且大大降低木材消耗。本文介绍了金川龙首矿试验这种高进路下向胶结充填采矿法的采场结构与回采工艺,并对胶结充填体——矿石间柱在回采过程中的稳固性进行了分析。

The conventional methods of mining in declined orcbody usuall resulted in large dilution, less productive capacity, low labour productivity and great unsafety factor in operation. In recent years, some mines have undertaken developmental experiments on mining methods such as sublevel open stoping in declined middle-thick orebody, overall

用常规采矿法开采倾斜矿体损失贫化大、采场生产能力小、劳动生产率低、操作不安全等。近些年来一些矿山对采矿法做了改进试验,对倾斜中厚矿体采用分段空场法、倾斜薄矿体采用留矿全面法,它们在实践中大都获得了好的技术效果,不同程度地解决了上述存在的问题,是目前开采这类矿体较为行之有效的采矿方法。这些采矿法都以空场法为基础,又具有同类或其它类采矿法的形式和特点,是两种采矿方法的组合。这种组合采矿法以注重协调采矿工艺、设备和采场结构三者之间的内在联系,从而兼备不同采矿方法的特征和优点,形成适应性较强的一种采矿法,很可能是今后倾斜矿体开采的一种重要途径。

In China,all of the gold veins are the mesothermal deposit with altered rock in a crushed zones and the hypothermal deposit with quartz vein, which are complicated and varied in configuration, small sizes in occurrence and poor in stability of ore and rock. The main mining methods used at present are shrinkage (42.58%) , open stoping (25.86%) , and backfilling (31.46%) .

In China,all of the gold veins are the mesothermal deposit with altered rock in a crushed zones and the hypothermal deposit with quartz vein, which are complicated and varied in configuration, small sizes in occurrence and poor in stability of ore and rock. The main mining methods used at present are shrinkage (42.58%) , open stoping (25.86%) , and backfilling (31.46%) . In the past 40 years, the mining technology with the local conditions was creatively developed and innovated in China's gold mines. For example, the development and application of shrinkage stoping with full face,hydraulic filling technology, trackless equipment, roof-bolting technique, large diameter longhole mining with high efficiency etc. have made the mining technology for gold mines to be innovated. However, there exist the problems on high loss and dilution of ore, low capacity in stope, long mining cycle, high labour intensity, low mining strength, poor mechanization and unbalanced in the development of mining technology etc. In the future, the efforts to research and deploy the mining methods, modify and perfect the roof support techniques and improve the mechanization should be made in the mining of gold deposits.

我国脉金矿床均系中温热液破碎带蚀变岩型和高温热液石英脉型,其形态复杂多变,埋藏规模小,矿岩稳固性差。目前所使用的采矿方法主要有留矿法(占42.58%)、空场法(占25.80)、充填法(占31.46%)。40年来,中国黄金矿山因地制宜创造性地变革和发展了采矿工艺技术,如留矿全面法、水力充填采矿技术、无轨自行设备的使用,顶板加固技术、大孔落矿的高效采矿方法的使用等,使黄金矿山的采矿技术为之一新。但目前尚存在损失贫化大、矿块生产能力小、回采周期长、劳动强度大、开采强度低、机械化水平仍然不高、开采技术发展不平衡等问题。今后在金矿床开采中应致力于新的采矿方法研究和推广应用,改进和完善护顶技术,提高机械化水平。
