Often adopt general discrete meta software UDEC to carry out numerical simulation to the strata movement model in mining engineering.But UDEC software need to be done a large amount of complicated work when manually setting up the coal rock layer model, manual calculations and assignment as to coal rock layer thickness, coordinate, character and joint character, primary stress, boundary stress etc. waste time and energy, and very easily make mistakes.Visual Basic 6.0 is visual, the OO development languages under windows platform, can be with code and data integration to independently in object in its programing system, and a large amount of work is completed by corresponding object.
Adopt strata movement numerical simulation automatic Building modeling method, based on VB6.0, the structure thinking of each module is as follows:
(1) data input and preservation module: can take full advantage of the controls such as label, text box, check box, order button in VB6.0, make I/O Interface clear, reduce the user and input the workload of raw data, and avoid various maloperations.Program with VB6.0 establishment is compiled into it portability that executable file can improve program, makes it in the situation that leave the VB operating environment and still can normally move.Simultaneously, model file and language output file that program is preserved can be used as raw data by the UDEC software transfer, for correctly resolving of rock pressure [in mine model provides data basic.
(2) data operation module: in VB6.0, the rock stratum is defined as custom variable group layer, the joint is defined as custom variable group joint, and with each mathematics and mechanics parameter as its dissimilar property value.After the typing raw data, at first program is assigned to data corresponding set of variables attribute, then property value is calculated.The computing thinking of coal rock layer coordinate points take in the lower left corner as true origin at first to define the coordinate points of the 1st layer, then shows out successively the coordinate points of other layers with loop statement For.Joint starting point computing can be with obtaining with the same method of rock stratum coordinate points computing.For selected every one deck, the strike joint spacing equals this coal rock layer thickness divided by the strike joint number of plies, and when the strike joint number of plies greater than 1 the time, vertical joint answers the interval to divide, thereby increases a starting point.
