摘要
根据矿井基本控制网的基本参数对互相贯通的巷道参数进行不断测量,有利于做好矿井的顺利贯通,在贯通点互相对接,由于原基本控制网导线点受井下巷道采动影响会发生位移动,出现误差偏移,造成贯通误差。提出了井下基本控制网受采动影响后,要对原控制网基本参数的误差进行测定和精度评定的方法,以及时更好的控制巷道的相对贯通工作。结果表明:对井下基本控制网基本参数及时进行优化设计改造非常必要和可行。
Mainly according to basic parameters of mine basic control network interpenetration to continuous measurement of roadway parameters benefitting mining smoothly, in the breakthrough point abutting each other, due to the original basic control network traverse points underground roadway mining would have a mobile, offset error, and breakthrough error. The error of the basic parameters of the original control network was determined and the accuracy of the basic parameters of the control network was settled and the accuracy assessment method was put forward. The results showed that the basic parameters of the basic control network in the underground mine was very necessary and feasible to optimize the design.
