Problems solved by technology

Under the condition that there is water in the blast hole, it is difficult to accurately measure the actual hole depth due to the complicated water quality in the water hole, and it is also difficult to achieve the desired effect by measuring the depth of the water hole with instruments such as laser measuring instruments.
Mine surveying and mapping Figure 1 Generally, 3 to 4 people are required to collect data on the spot and then carry out in-house operations to complete it. The on-site operations are not only in a harsh environment and the workload is heavy, but also due to the hand-painted blast hole diagrams, the precision and accuracy are not enough. After computer input and actual The situation in the explosion zone is quite different

Description

technical field [0001] The invention specifically relates to a blasthole depth measuring instrument and a measuring device, belonging to the technical field of blasthole measurement tools. Background technique [0002] At present, mine blasthole measurement in mines is basically carried out with hand-held measuring ropes. Under the condition that there is water in the blast hole, due to the complex water quality in the water hole, it is difficult to accurately measure the actual hole depth. It is also difficult to achieve the desired effect by measuring the depth of the water hole with instruments such as laser measuring instruments. Mine surveying and mapping Figure 1 Generally, 3 to 4 people are required to collect data on the spot and then carry out in-house operations to complete it. The on-site operations are not only in a harsh environment and the workload is heavy, but also due to the hand-painted blast hole diagrams, the precision and accuracy are not enough. After ...
