【摘要】 针对地质图件中急倾斜煤层尚未实现计算机绘图的问题,本文提出了立面投影图绘制的数学模型,并且用VC++语言编制程序来实现了数字绘制急倾斜煤层立面投影图,不需要其它商业软件的支持。程序可以全面取代传统手工制图,它克服了手工制图的缺陷,可以准确、快捷地实现坐标投影变换等操作,能显示出不同水平的巷道、煤层走向、赋存等情况,为煤层的开采,巷道、工作面和石门的设计布置提供依据,具有较强的实用性和经济性。更多还原

【Abstract】 In view of the problem of the difficult of mapping the facade of steep-inclined coal seam,the mathematic model of fa?ade projection is presented,which was realized by VC++,which doesn’t need other commercial software to support,it could replace the traditional handworked mapping,and overcome the shortages of the traditional means,and could realize projection transformation quickly and accurately,etc.The procedure could demonstrate the different horizontal tunnel,the coal bed trend,the occurrence and so on,providing the basis for coal bed mining,the tunnel,the working surface and Shimen’s arrangement,which has stronger usability and efficiency.更多还原
