In recent years, a number of tungsten polymetallic ore deposits were discovered in Guidong—Rucheng area, resulting in a remarkable breakthrough in the expansion of ore deposit type and ore deposit size. The ore deposits are of skarn type, altered granite type, structural alteration belt type, quartz vein type, greisen type, bedded type etc.

Firstly, the stope vacancy was monitored using CMS, taking cavity measured data as foundation, cavity three-dimensional model of the stope opening was created using Surpac software and gain the stope three-dimensional configuration and the actual boundary accurately. Then, the stope designed model and ore-rock interface digital terrain model were established according to the stope design material. Finally, using ore-rock interface DTM to cut cavity model or through Boolean calculation among the models, ore remains, mining total volume, mullock, backfilling, pure ore and dilution rate of stope N3-4 were calculated accurately, thus the large-scale stope mining index visible calculation was realized effectively.

This paper points out that the ore-forming pattern of this mineral deposit is ore-bearing basic-superbasic magma melting-crystalline different and ore magma impulse injection in turn. It indicates there maybe has a ore shoot in the bottom of III rock body(interrupted below 650m), and advises to geophysical prospecting in the mining shaft.

The study of ore-forming rules indicates that the shearing force came from interaction of plate-plate is the initial force, which result in remelting of deep rock. Early formed faults and later dome structures provide favourable passage-way for ore-material migrating. Finally due to complete circulate convection, ore-material experience a process of complete differentation and begin to crystal and settle in certain circumstance. In some favourable tectonic zone ore-forming material enriched to deposit.

Base on above studies, some conclusions were obtained as follows:(1) ore-forming background of the studied ferromanganese crusts are mainly controlled by intensity of Antarctic Bottom Waters and variations of material source;(2) it is confirmed that the ferromanganese crusts are mainly hydrogenetic and their composition are affected by volcanic and continental material simultaneously; there are no obvious phosphatization reconstruction and element reaction occurred in them, so they have important paleoceanological significance;(3) from researches on element occurrence modes in the new-type ferromanganese crusts and the lying sediments, it is proposed that there is no great biological affection on the crusts formation and their composition mainly came from the adsorptive action of the ferromanganese oxides in them;(4) two major types of ore-controlling factors are identified through compilation of ore-controlling factors, which are geological and oceanic factors;(5) considering the long-term variation trends of the crusts composition, combing the U-series and 10Be isotope dating results, it is proposed that the ore-forming processes of ferromanganese crusts in the studied areas can be divided into three major stages (5.6~2.8 Ma, 2.8~2.7 Ma and since 2.7 Ma), and then the activities of AABW since the Late Miocene, changes of input flux coming from volcanic and continental material are confirmed.
