| Guizhou Province in Southwest C hina is one of the main distribution area of fine disseminated gold deposits in China. However, Southwest Guizhou very complex geological conditions, ore genesis gold deposit types, changes in the larger lateral variation obvious, extension ore-body pinches out and no rules to follow. In the development of this type of gold ore body’ shape due to the uncertainty, and the lack of three-dimensional visibility in two-dimensional maps geological studies, it is difficult to grasp the overall distribution and form deposits in the ore body, can not reasonably be mine planning, thus guiding production. Inefficiencies, depleted serious waste of resources and other phenomena caused by the mining process. Therefore, an accurate grasp of the fine disseminated gold ore body morphology, mode of occurrence of gold deposits in the efficient development and utilization is a problem.In the previous article on the results of existing research, Anlong County, Guizhou Province as the research object is Getang Gold. Its complex orebody morphology analysis, with the use of professional mining engineering software to build a three-dimensional geological model, and the results of different means o n exploration of three-dimensional solid model from ore bodies were additional corrected. The main contents are as follows:1. Gold deposit production reports collected, the relevant geological data storage maps, geological profiles, drilling bar charts, etc., to understand Getang Gold Deposit regional geological setting and geological conditions;2. Using mining engineering software, 3DMine, to entry Getang Gold drilling information, establish Getang gold mine drilling database; establish mining terrain model; Getang use GO LD geological profile and drilling database ascertain ore body boundaries, establish three-dimensional solid model of ore body and F35 fault model;3. In Getang Gold test stope through the dual- frequency ip method to probe into the work, and the frequency domain, sweeping staircase and frequency domain symmetry plane quadrupole sounding work, based on the detection results caused by abnormal delineated ore body, and use different sequences of polar distance in non-horizontal strata(Index mode pole pitch sequence, Logarithmic pattern pole pitch sequence), then sounding effects were compared; dual- frequency ip method to detect the outcomes of the three-dimensional solid model of ore body based drilling database established to complement revised, and be more able to form a true reflection of gold ore body model;4. analysis of the three-dimensional geological model in the mining design, application of numerical simulation. Use 3DMine mining engineering software provides the DTM surface contour generation function, based ore-body modeling of ore were drawn roof contour map, ore bottom contour map, aim at the Er-Longkou Mining Section of Getang gold, Shang-Mianlang block section, No.13 ore-body had been done a exploition design, adopt 3DMine—C AD—PHasee2, with its coupled mode to carry out numerical simulation. |
