【摘要】：普通双人操作型钻机进行中深孔采矿时,通常使用传统的测量方法。这种测量方法比较粗糙,炮孔定位和施工精度较低,会造成爆破孔分布不均或定位不准确,无法严格按照设计施工,容易导致爆破后出现超挖、欠挖、采场轮廓不规则等情况,甚至揭露F1冒落。本文针对台车中深孔采矿作业特点,提出了一整套创新的测量技术方案,在三山岛金矿中深孔采矿方法的试验中成功进行了应用,大大提高了现场作业的精度、效率和安全性,保证了中深孔采矿整体的施工质量和安全质量,并在后期爆破中取得了良好的爆破效果,在同行业其他矿山的生产中具有推广和借鉴意义。
[Abstract]:The conventional measuring method is usually used in the middle and deep hole mining of common double operation rig, which is rough, low precision of hole location and construction, which will result in uneven distribution of blasting holes or inaccurate positioning of blasting holes. It is difficult to strictly follow the design and construction, which can easily lead to over-excavation, underexcavation, irregular outline of stope after blasting, and even expose F1 caving. This paper aims at the characteristics of medium and deep hole mining operation of bench wagon. A set of innovative measurement technique scheme is put forward, which has been successfully applied in the test of the medium and deep hole mining method of Sanshandao Gold Mine, which greatly improves the accuracy, efficiency and safety of the field operation. The construction quality and safety quality of the whole medium and deep hole mining are guaranteed, and good blasting effect is obtained in the later stage of blasting, which is of great significance in the production of other mines in the same industry.
