井下导线测量及后视目标照射装置创新优化研究

Research on Innovation and Optimization of Downhole Traverse Measurement and Rearview Target Irradiation Device

井下导线测量是矿井作业的重要前置内容,通过实施井下导线测量作业可以得到立体的空间三维坐标系统,同时对各控制点进行坐标化管理可以实现控制点的精准定位,进而为井下巷道、硐室以及回采面的精确测绘与标定奠定了基础,还可以在日常性井下贯通测量的基础上满足井下开采作业的数据要求。基于井下导线测量对后视目标照射装置进行了优化,通过使用矿灯替代垂球并结合半弧形罩与反光装置的优化,在测量精度与测量效率方面实现了提升。

Downhole traverse measurement is an important front of mining content.The implementation of the downhole traverse measurement can get the three-dimensional coordinate system of space.Meanwhile,coordinates management of each control point can realize accurate positioning,which lays a foundation for accurate mapping and calibration of underground roadway,chamber and mining surface and meets the data requirements of underground mining operation.In this paper,the rearview target irradiation device is optimized based on downhole traverse measurement,and the measurement accuracy and efficiency are improved by using mining lamp instead of vertical ball and combining the optimization of semi-arc mask and reflective device.
