In order to overcome the disadvantage of volume effect and improve prospecting precision of MT, the paper puts forward a multi-channel telemetry method of stratum resistivity for linearity processing exploring depth and electromagnetic frequency in the local area, which creates a crresponding relationship between stratum resistivity and sounding line, and a multi-channel observation system is designed accordingly to explore the resistivity of underground ledge.

为克服大地电磁勘探中"体积效应"的缺点，提高探测精度，提出多道遥测地层电阻率法，该方法是在一个局部区域内，将勘探深度和电磁波周期进行线性化处理，使得地层电阻率和测深曲线建立对应关系，并据此设计了一个多道探测地下矿层电阻率的观测系统。

Many sparsely disseminated and nodular pyrite can be found in the oil shales. With the oil shale occurring in the bottom, trona, salt, dolomite and silty mud rock also the oil shale make up many sedimentary rhythms.

其内可见大量星点状、结核状黄铁矿，并作为天然碱矿层的直接底板与天然碱、盐岩、白云岩及粉砂质泥岩构成了多个韵律旋回。

Oil were recently discovered in brecciated limestone, micrite kimestone and dolomitized limestone associated with Jinding lead-zinc deposits.

兰坪坳陷的油气主要见於金顶矿区的下含矿层，储层主要为上三叠统三合洞组的灰岩和角砾状灰岩石。

The chromite deposits in the Muskox Complex occur only in feldspathic peridotite.

野外工作研究发现，青龙哨角砾状磷块岩顶板的磷锶铝石矿层和高岭土黏土岩二者呈超覆式不整合接触。深入研究发现其具有陆相磷块岩的许多特征，而没有浅海相磷块岩的原生沉积构造特征。

The invention comprises the procedures that:(1) a horizontal section (13) and a vertical section (14) of a horizontal well (10) are formed in a manto (30) by the horizontal well technology;(2) injection wells (11) and recovery wells (12) which are alternately spaced and arranged are formed;(3) mining is carried out according to the traditional in situ leaching method.

本发明包括下列步骤：①通过水平井工艺在矿层(30)中形成水平井(10)的水平段(13)和垂直段(14)；②形成交替间隔排列的注入井(11)和采收井(12)；③按照传统原地溶浸方法进行采矿。

Be gotten by stoping as horizontal ledge thinner and thinner, its stability problem more and more be taken seriously.

随着水平矿层被回采得越来越薄，其稳定性新问题越来越受到重视。

The copper-bearing sulfide horizon of the Qinglongtan deposit underwent not only intense structural reformation but also superimposition of skarn-type mineralization after the formation of massive sulfide ores.

文章综述了柴北缘地区的VHMS型Cu-S矿床－青龙滩式矿床，指出其容矿岩石为加里东造山带中被改造过的岛弧火山岩，该矿床中含铜硫化物矿层形成后不但遭受过构造的强烈改造，而且也受后期矽卡岩化的改造和叠加。

The layer of solid KCl is so thin in depth、so small in size、 and so low in grade that it is too difficult to exploite it. Besides that, only 1/3 of the liquid KCl can be expoi ted due to the mining method of well and canal drainage which is being used now. Therefore, it is one of the key problems to exploite the liquid KCl as possible as we can and to turn the solid KCl into explo itable liquid deposit in Qarhan salt lake. So the idea of dissolving and driving exploitation has been suggested. This paper will deal with three problems as follow

然而由于固相矿层薄、品位低而难以直接开采利用，加之目前对液相矿产只是纯疏干性开采，充其量只能采出1/3的液相矿，因此如何最大限度地开采液相矿产，同时将固相矿产转化成能直接开采利用的液相矿产是察尔汗盐湖开采中急需解决的关键问题之一，对此人们提出溶矿驱动开采的设想，本文正是以此为目的，着重研究以下三个问题

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。
