矿体

Ltd adopted the horizontal drilling technology to drill two horizontal ly-communicated remedy wells with large caverns in Weixi thinly-bedded rock salt deposit,which has opened up a precedent in the application of horizontal well d rilling technology in thinly-bedded rock salt mine in our country.

四川久大制盐有限公司长山盐矿，首次应用水平钻井技术，在威西单薄层岩盐矿体上，钻成两眼大溶腔外水平连通补救井，开创了国内单薄层岩盐矿山水平井技术应用之先河，多项技术、经济指标超过了其它类型岩盐矿山水平对接井，取得了良好的经济效益和社会效益。

A first decline was sunken to provide access to the ore body and trail mining was carried out in different stopes.

第一次沉降为我们提供了接近矿体的机会，公司在不同的采矿场进行了试采。

Iron ore-body,shaping as similar bed,vein,lens shaped and so on,extends NWW-trending with dips mainly to northern at angle 80°～86° and partly to southern at high a...

矿体形态为似层状、脉状、复杂透镜状等，走向NWW，倾向北为主，倾角80°～86°，部分近直立或高角度倾向南。

Former ore body is lesser, but latter grade of grade tall; is inferior, but dimensions is medium.

前者矿体较小，但品位高；后者品位较低，但规模中等。

And there is a general feature that the ore beds,which are generally small or middling gradient and whose strike and dip are along the fault belt,distribute alternately following the maturity of mineralization.

在小秦岭金矿田内，断裂构造控制着金矿床的产出，断裂带产状形态的变化、展布规律控制了矿体的形态、产状和富集规律，总结出缓—中等倾斜的矿脉沿断裂带走向和倾向普遍存在矿化强弱相间分布的特点。

Special drilling or adits outside orebody may be required.

可能要求在矿体外作专门钻探或坑探。

The stability of the goafs of Liangshi gypsum deposit is mainly influenced by the small thickness,water-absorption and low strengths of compression and shear of the upper walls of the orebodies;and by the clearages and bedding ;as well as the undergraound water activity and irregular mining.

两市镇缓倾斜石膏矿床采空区稳定性的影响因素，主要有矿体顶板硬壳——青膏层的厚度薄，易吸水软化，抗压抗剪强度低；区内局部节理发育、层理密集；地下水活动以及开采不规范等。

Based on the observation and statistics on the calcareous sandstone in the ore host layer in Shihongtan uranium deposit , this paper finds that the calcareous sandstone occurs on and off near the top or wash surface of the sandbody as beads-strings lens along the layer and concentres in the area where the orebodies are rich .

摘要通过对十红滩铀矿床容矿层钙质砂岩的观察和统计，发现钙质砂岩呈顺层、断续的串珠状透镜体分布，产出空间位置为砂体的顶底部或冲刷面，而且较集中的分布在矿体发育区。

In orde to obtain system optimization in high efficiency production and operation safety, the microcosmic problem of goaf treatment was brought into the creative design of mining method and the synergism of two problems was studied. Firstly, in view of the occurrence characteristics and mining conditions of catacalstic ore section of orebody No. 105 in Gaofeng mine in Guangxi province, considering the adaptability to different scale goafs in the ore section, based on mining environment reconstructing idea and continuous mining mode, a new mining method (mining environment reconstructing non-pillar sublevel-strip continuous mining method) was put forward. Then, some repr, esentative goafs were selected and their stabilities were calculated by discrete element method on the basis of differences of goaf scale, surrounding conditions and situ stress field. At last, the mining layout was adjusted on the basis of goafs stability analysis and the goafs were adjusted as a part of cutting engineering, blasting space or stope, so as to determine all kinds of goafs treatment schemes.

摘 要：为在生产高效和作业安全上取得系统整体最优，将碎裂矿段的空区处理微观问题纳入采矿方法创新设计宏观问题中，开展2种问题的协同研究：首先，针对广西高峰矿105号矿体碎裂矿段的赋存特点和开采技术条件，考虑对各种规模空区适应性，基于采矿环境再造和连续采矿理论，提出采矿环境再造无底柱分段分条连续采矿法；然后，根据采空区规模、围岩状况和原岩应力场等条件的差异，在所有采空区中选择具有代表性的空区，运用离散元程序对其稳定性进行计算分析；最后，在稳定性分析的基础上，灵活调整开采布局，将采空区调整为部分切割工程、自由爆破空间或采场，从而确定出各种规模空区的处理方案。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
