Geological work in the coal mine in Computer Application


Operators rock mining and stripping the amount of media bore. Quantitative study of the exploration degree 4 Usually, people used to the 74 coal geological exploration mainly summarized as two major aspects of coal and construction, there is no fur in the levy to the extent of its exploration and quantitative indicators,[link widoczny dla zalogowanych], only qualitative, experience in pre-divided Several exploration type, according to the provisions of the basic engineering requirements of space exploration. Can use the concept of regional variables in geostatistics variables studied geology of coal, with the geostatistical method of coal thickness, ash content, including spatial patterns of refuse rate, find the best unbiased estimator and estimated variance (mouth). . Estimation accuracy of the estimation variance is the R degree. Kriging estimates the average lead standard deviation () is the estimated coefficient of error of 1 degree of absolute control of one degree of estimation error on the relative degree of Sao m (m is the estimated average value of the variable.) Therefore, the average coal seam thickness can be estimated using standard deviation and coefficient of two indicators the degree of control, will characterize the wall thickness of the coal exploration degree, that is,[link widoczny dla zalogowanych], the extent of reserves, exploration. The geological structure is natural, due to geological structures are complex, and its curved shape is different tectonic feature points,[link widoczny dla zalogowanych], feature lines and characteristics of surface groups from Taiwan, so the exploration of different structural characteristics, measuring exploration indicator of the degree will not be simple and uniform, such as: the exploration of folds and faults have different levels of exploration and quantitative indicators will vary from the preliminary study shows; the rules are set to fold, you can use one by one in the folds of the song to the profile, the 'hole ask a wing fold from the mean length of horizontal projection, * almost no distortion can fold geometry} hole spacing equal to the fold n fold a wing length of horizontal projection of ~ when is the best cloth 0 hole spacing. Degree of control is the fault of the exploration hole distance, hole number, breaking away from the function. Reference to coal resources exploration specification, can be pitch 500m, down from 30m, four-hole with a two-line control of the situation as a standard, than to list ��fjJ degree of control on the fault Bai Qing c = () where: C one by one inference degree of control faults, C �� 1.0; n holes one by one the number of control faults' �� h off one by one inferred from the unit m, d one by one pitch, unit 121.5 with a secondary analysis of geological structures inferred j # computer processing ore geological information, not only can complete the hand in a variety of structural analysis and calculations, but also assisted inferred fault structures, determine the location of fold hinge, suggesting that local fluctuations extreme point, solving planar, the advantages of linear structure and orientation. Computer display screen image to provide for such analysis to infer a convenient, simple means but the image of senior computer graphics, so that accurate three-dimensional graphics, realistic geological analysis to show the people in front of the geological structure of the work infer much convenience. 6 Classification and Mining Mine Evaluation of geological conditions in the analyzed and summarized the work into a computer data analysis and processing. In recent years, to meet the comprehensive study on the exploitation of the needs of geological conditions, in particular, to meet the needs of mechanized mining, development and use some of the more comprehensive evaluation of new methods which; 6.1, etc. This section Index Act Methods section of the block 6.2 The fuzzy comprehensive evaluation method of fuzzy comprehensive evaluation principle units of mechanized mining geological conditions for the evaluation, to selection for mechanized mining section of the geological block. 6.3 Evaluation Method and gray blur comprehensive mathematical evaluation method similar to Taiwan, J {{_ gray system theory mechanized mining geologic evaluation of service parts at the fully mechanized units, aimed at optimization of geological blocks for the mechanized mining section. 6.4 Comprehensive evaluation in structural composite index, such as block Indexation method, fuzzy mathematical evaluation method, based on the geological conditions on mechanized mining comprehensive evaluation,[link widoczny dla zalogowanych], to selection for mechanized mining section of the geological block. 7 geological maps drawn in the computer graphics display and processing capabilities continue to improve, and now, in DOS and AUTOcAD system software support, help with computer embroidery design can be drawn based on geological maps of various parts, such as borehole histogram , coal plan, various equivalent coil,[link widoczny dla zalogowanych], sections, elevation drawings and perspective and so on. The drawing of geological maps, greatly changed the face of coal mining technology of geological work, improve work quality and efficiency. Computer graphics has become a computer application of geological work in the coal mines of the important aspects. In summary, the geological work in the coal mine in the computer application in the ascendant, is extended to the deeper and broader areas, a trend Yi mine geological work will promote the technological upgrading of traditional and modern geological work activity assigned.
