在加強技術管理、開展关於採鑛損失率和貧化率計算工作的現階段,鎖山採鍍埸的取樣問題始終末得到完滿解决。在幾個進行損失率、貧化率試點工作的鑛山裡,採鑛场用內仍用刻槽取樣法進行取樣,其迅速遠跟不上生產的需要,人力和時閭的消耗也很大。当然並不是所有鑛床均能使用机採法,適合使用机採法的鑛山有的现正試用机採打眼法來代替刻槽取样法,並已取得一定成績,但对机採打眼浊眼距的安排和眼的深度尚須進行 At the present stage of strengthening technical management and carrying out work on the calculation of mining loss rate and dilution rate, the sampling of the lock of the mountainous area is still not completely solved. In several mines where the loss rate and the depletion rate were piloted, the sampling in the mining area was still sampled using the groove sampling method, which quickly failed to keep pace with the needs of production. The manpower and time laps were also greatly consumed . Of course, not all deposits can be used machine mining method, suitable for mining method mining machine is now some of the trial machine Capping instead of groove sampling method, and has achieved some results, Distance arrangements and the depth of the eye still have to be carried out
