易门铜矿地下开采,深孔给向工作量大,国内又未见有合适的深孔给向仪。过去深孔给向测量是采用罗盘人工测量给向。该方法工效低、劳动强度大,测量精度差,影响落矿质量。为了提高深孔给向的效率和精度,改善测量人员的作业条件,易门铜矿凤山分矿与云南冶金专科学校合作研制“深孔给向仪”。该仪器由三脚架、装有水平气泡的基座,调态对中国的长条形滑板、罗盘仪和光
Yimen Copper Mine underground mining, deep hole to the heavy workload, there is no suitable domestic deep hole to the instrument. In the past, deep hole orientation measurements were made using compass manual measurements. The method is inefficient, labor-intensive, poor measurement accuracy, affecting the quality of ore falling. In order to improve the efficiency and accuracy of deep hole orientation and improve the working conditions of surveyors, the “Deep Hole Directional Instrument” was developed in cooperation with Yunnan Metallurgical College by Fengshan Mine of Yimen Copper Mine. The instrument by the tripod, with horizontal bubble base, adjust the shape of China’s long strip skateboard, compass and light
