矿体

Thickness of ore bodies and silver grade are controlled by breccia bodies.

矿体厚度和工业矿体银的品位也受角砾岩体控制。

The correlation of the sandstone type ore bodies and limestone breccia type ore bodies is discussed, and the deep ore body is forecasted.

初步讨论了砂岩型矿体和灰岩角砾岩型矿体的成因联系，对矿区深部找矿前景进行了初步预测。

Such saline ore bodies as the gypsum and lazulite , etc. are presenting a more intact ring, and the ore body is distributed all around. The annular top has already been destroyed, have shown its primitive shape may be one salt dome.

硬石膏和天青石等盐类矿体在整体呈一较完整的环形分布，矿体均分布于四周，环形的顶部已被破坏，展示了其原始形态可能为一盐丘。

The ore is characterized by veinlet structure, net-veined structure and comb structure, and the gradual outward transformation of ore structure from veined via net-veined and veinlet-disseminated to disseminated is common. These characteristics in ore fabrics and the occurrence of cryptoexplosive breccia are strong evidences that Songxi Ag-Sb deposit is a hydrothermal deposit.

矿体中发育大量的脉状、细脉状、网脉状和梳状等充填交代构造，由矿体向围岩常可见脉状→网脉状→细脉浸染状→蚀变围岩的渐变过渡现象，这些构造特征以及热液破碎角砾岩的出现，为嵩溪银锑矿床的浅成热液成因提供了有力证据。

This study was only focused on the No.Ⅰore body. Based on detailed logging and dating results, it is considered that mineralization of the Cu_Au porphyry occurred in Late Jurassic. The formation of the ore body is related to the Late Jurassic augen quartz phenocryst_bearing hornblende_quartz diorite porphyrite intrusion（J3δομ）.

通过对雄村铜金矿床Ⅰ号矿体详细的地质编录和测年成果，发现雄村斑岩型铜矿床形成于晚侏罗世，矿体的形成与晚侏罗世侵位的、含眼球状石英斑晶的闪长玢岩（J3δομ）有关，成矿岩体呈不规则的岩枝状，全岩矿化，岩体中Au的平均品位大于1g/t，Cu含量大于0.7 %。

The study of the geological characteristics, ore-forming condition and genetic type from the Pingdingshan gold deposit, shows that the cryptomerous diorite and dioritic porphyrite in different stages formed a vein rock zone with gold containing ore bodies in the area, and five vein ore bodies were blocked out by spreading out with the NNE direction in the field.

黑龙江嘉荫平顶山岩金矿床的地质特征、形成条件和成因类型的研究表明：矿区内不同阶段的细晶闪长岩、闪长玢岩形成一个含金矿体的脉岩带；矿床范围内圈定5条呈脉状沿北北东向展布的矿体；矿石类型为石英脉型和蚀变岩型；金以裂隙金、晶隙金和明金为主，以银金矿的形式存在，且主要与石英、黄铁矿、毒砂和水云母共生；成矿作用分为热液期及表生期，其中热液期又分为4个成矿阶段，即纯石英阶段，黄铁矿毒砂石英阶段，黄铁矿毒砂水云母石英阶段和石英碳酸盐阶段。

Focusing on them, author has been investigating in open country and collecting, arraging and analyzing material for one and a half year. After having done the study on the new deep prediction, author presents new opinion on the base of part of precious geological opinion .1, Xiaohe deposit direction and turn are mainly controlled by the second structure rochet vault in the back of Bigsnown mountain. It is conjectured that the axis extent with the current direction to the 180# exploring line and turn to northwest-southeast direction. During the extension, the deposit body would extend from deep to low instead from low to deep. The turning place was level corresponding to the core of rocket vault.2, There are a chain of radiate blind regmagenesis controlled by the rocket vault.

笔者针对这两个问题，通过一年半的野外实地调查和室内资料收集整理分析，在进行了新的深部找矿研究工作之后，在认同前人部分地质观点(即小河～石门坎矿带的连续是存在的)的基础之上，又提出了新的观点，即： 1、小河矿床矿体的走向及转向位置主要受大雪山背斜的次级构造火箭山穹隆控制，推测其轴线将沿现在的走向，延伸至180#勘探线附近发生转向，轴线方向逐渐转为北西——南东方向，同时矿体从由浅至深逐渐变为由深至浅的延伸状态。

In order to overcome some difficulties in mechanized kaolin mining, such as the weak roof, hard ore body, high toughness, it is necessary to apply long hole standing shot technology before the mining activity so as to improve the mechanical cutting efficiency and meet the demand of blocks degree.

为了解决煤系高岭土矿机械化开采存在顶板软弱，矿体相对煤炭质地硬，韧性大，矿石块度要求适中等难题，有必要在开采前采用预先对矿体进行充分合理的松动爆破，以提高机械切割效率及满足矿石块度适中的要求。

After study on technical mineralogy properties of the upper and deep layers of an iron ore bed in Anshan ,mineral processing tests were tried out.

在分析鞍山某铁矿床上部矿体和深部矿体矿石的工艺矿物学特征的基础上，进行了选矿探索试验研究，首次针对同一矿床不同深度矿体采用不同工艺流程，取得了较好的选别指标，为该铁矿床的全面开发利用提供了科学依据。

Thirdly, it analyzes and studies in detail Surpac mechanism and the relevant concepts on constructing the model of mineral deposits and mining engineering systems according to the modeling procedure and the actual conditions of Jinchuan"s mines. Based on these:Lit points out some differences between the western countries and China in the practice of the geological data record, explores the inputting data on computers performed by more people at the same time and the method to improve constructing the data-base and finished the data-base of Jinchuan mineral deposits;2.It puts forward the steps and flow chart to construct the solid model and brings forward the scheme of "first individual then whole to set up Jinchuan mineral deposits geological model, summarizes some experiences for constructing the complicated geological ore body of the high accuracy: add control lines, add auxiliary demarcation lines +control lines, the operation of intersection, cross and incorporation between solid bodies and plane and section combination. The above-mentioned methods applied to construct the mineral deposits solid models of four mine areas in Jinchuan; 3.lt studies and presents the detailed flow chart of constructing block and grade model, analyses the workable scheme in setting up the block and grade model of main ore body for Jinchuan mineral deposits and also sets it up.

接着，按建模流程并结合公司矿山实情，详细研究、分析了Surpac构造矿床模型和采矿工程系统模型的机理、有关概念，在此基础上：(1)指出了西方国家与我国在地质数据记录习惯方面存在的一些差异，探索出多人多机同时录入、提高建库效率的方法，建立了金川矿床地质数据库；(2)研究并提出了构造实体模型的步骤和流程图及&先分后整&建立金川矿床地质体实体模型方案，总结出建立高精度复杂地质体模型几点经验：添加控制线法、添加辅助分界线+控制线法、实体间的交、叉、并运算法及平剖面图联合法，建立了金川矿床四个矿区主矿体的实体模型；(3)研究并提出了建立块模型、品位模型详细流程图，分析了建立金川矿床主矿体块模型和品位模型的可行方案，建立了金川矿床主矿体的块模型和品位模型。
