摘要
在建 (构 )筑物下采煤时 ,引起地表沉陷 ,为了保护地面的建 (构 )筑物 ,需要留设保护煤柱 ,传统方法是利用手工计算压煤边界及压煤量 ,这样给实际生产带来不便 ,不利于提高工作效率。文中主要研究如何以GIS软件 (AUTOCADMAP2 0 0 0 )为基础来实现建 (构 )筑物下压煤边界及压煤量的自动确定。
Coal mining under buildings (structures) always causes surface subsidence and some protective coal columns are therefore required to be kept so as to protect surface buildings (structures). The traditional method for such purpose is to calculate by hand the boundary and quantity of protective coal columns, which brings about much inconvenience to actual production and affects the working efficiency to some degree. In the paper, a research on determining automatically boundary and quantity of protective coal columns under buildings (structures) is made on a basis of the software GIS (AUTOCAD MAP2000).
