摘要采煤作业循环图表是采煤作业规程中重要的组成部分，其图形中线型具有代表意义，但在根据具体情况而使用AutoCAD绘制采煤作业循环图表而表达不同工序过程中，会因为重复操作同一过程而显费力。比如在绘制表达“割煤”工序的“实体箭头”时，通常会采用填充、复制等基本方法，而在绘制“移输送机”工序的图形时，只有保证其间距相等且线条平行才能显得美观。这些问题会伴随在绘制采煤作业循环图表的整个过程。[1]39704

AutoCAD中自带的线型，可分为简单线型和复杂线型，简单线型由短线、空白、点组成，复杂线型由简单线型、形组成，其中形包括字符和图形。采煤工作面循环作业图中所用线型，可分为复杂线型和特殊线型。比如：检修线型为复杂线型，割煤为特殊线型。
本文使用AutoCAD附带工具Express tools中的make shape命令制作形，在其自带的线型文件中定制采煤工作面循环作业图中所需的复杂线型；利用AutoCAD中的开发语言VBA，开发采煤工作面循环作业图中所需的特殊线型。以便在绘制采煤工作面循环作业图时，能够快速、准确。

Abstract
Mining cycle diagram of operation is the important part of the coal mining operation procedures, its linear representative in graphics, but in according to the specific situation and use AutoCAD draw various graphics and express different processes in the process, show effort by repeating the same process. Such as expressed in drawing process of the real arrow cut coal, usually use the basic method, such as filling, copy the drawing moving conveyor process graphics, only guarantee the equal spacing and parallel lines will appear beautiful. These problems will be accompanied in the whole process of coal mining activity cycle diagram drawing.
Own lines in AutoCAD, can be pided into the simple lines and complex lines, simple linear consists of short-term, point blank, complex linear composed of simple lines, form, shape including characters and graphics. The coalface lines used in circular flow diagram, can be pided into complex linear and special lines. Lines, such as: maintenance lines for complex cutting coal for special lines.
In this paper, using AutoCAD with tools to Express the make of the tools shape command production form, the mining face in its own linear file custom cycle operation diagram for complex linear; The mining face, development language in use of AutoCAD VBA circulation homework required special lines in the figure. In order to map the coalface cycle operation, quick and accurate.
Key words: AutoCAD, mining face circulation flow chart, linear, customization, VBA, development
