摘要
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。
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
shrinkage stoping in declined thin orcbody. Most of them hava got desirable technical' results in practice for having solved the above problems to some extent, and are more effective at present,Having the forms and characteristics of the same or other methods that based on open stoping,the above developmental methods are the combination of two mining methods.With the coordination and interconnections between technique, experiment,and stope structure being emphasized,the composite one has the characteristics and advantages of various methods.lt is more adaptable and will very possibily be an important way to the mining of the declined orebody in future.
