摘要
针对矿山在使用全站仪延伸中腰线中存在的实际问题,利用半导体激光技术开发研制了JCZ激光中腰线延伸仪。该新型延伸仪体积小、精度高、携带方便、操作简单,对控制巷道掘进、回采进路质量可发挥较大作用,实践表明,该仪器的误差可满足矿山生产实际的需要,具有推广应用价值。
Aiming at the practical problems existing in extending centre and gradient lines with total station instrument, the JCZ laser centre and gradient lines extension meter has been developed by using semiconductor laser technology. This new centre and gradient lines extension meter is small in size, light in weight, high in accuracy, convenient to carry and simple to operate, can play more important role in the quality control of road- way excavation and stoping drift. The measurement error of the extension meter can meet the needs of actual production, so has a promotion and the application value.
