The analysis result shows that the basement fault anomalies control a few major large hidden batholiths and their associated orefieldsthat the anomalies of cover structure confine most Cu-Au deposits and Fe-Cu deposits within their scopethat the geochemical anomalies and lithofacies-paleogeographical anomalies are major geological factors leading to trataboundness of some Cu-Au depositsthat the anomalies of rock operties provide the favorable chemical and physical conditions for the ore-forming process, including the seepage, circulation,convergence and deposit of ore-bearing hydrothermal solutionthat the anomalous ctive stage of Mesozoic magmatite is almost consistent with the major mineralization epoch of the Fe,Cu deposits, and the structure of multi-levels,and the zoning in magmatic system determine the spatial distribution of the mineralization system.

Several tens of superlarge hydrothermal gold deposits related to volcano subvolcanic rocks have been defined in the world since 1980s. It is of great importance, both economically and theoretically, to study this type of gold deposits. The newly discovered Jinchang gold deposit, Heilongjiang Province, is one of this type of gold deposits, which is hosted by breccias bodies that are associated with volcano-subvolcanic rocks. More than 30 t Au resource has been proved after preliminary exploration by the 5〓 Geological Party of Gold Headquarter.

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。

This kind of sulfide ore is relatively refractory and it is difficult to improve production ibexes, with high cost and low benefit. During 1988 to 2000, the per-product ability is 157.5 ton per day, primitive mineral tin grade is 1.89% and obtained 52~54% tin concentrated, with 51.06% recovery. Tin grade of 1.5% make mining and processing keep equal.
