基于影响椭圆法的保护煤柱留设及其系统实现

The Achievement of Mine Protection Pillar Leaving and its System Based on the Affeet Ellipse Method

文中根据煤矿区保护煤柱留设原理以及影响椭圆法设计保护煤柱的步骤,在AutoCAD平台上进行二次开发,构建了保护煤柱自动设计系统。以移动角参数为依据采用几何方法确定影响椭圆的半轴长度,利用AutoCAD二次开发,实现了影响椭圆半轴长度的自动计算及保护煤柱留设的计算机自动绘图。在此基础上,应用所开发的系统进行工程保护煤柱设计,验证了系统的可行性。

In the paper,the author establishes the automatic design system of protective coal pillars on the base of second evelopment on the AutoCAD platform according to the theory of protective coal pillars and the steps of influencing ellipse method in setting protective coal pillars.The author defines the semi-axis length of the influencing ellipse the parameters of surface movement angle adopting the geometric method and using the AutoCAD second development.The author realizes the automatic calculation of the semi-axis length of the influencing ellipse and automatic drawing the protective coal pillars by the computer.On this basis,the author uses the developed system to the design of protect the coal pillar and verifies the feasibility of the system.
