The rope core winch is a specialized equipment used in geological drilling, mineral exploration and other fields for rope core drilling technology. It mainly cooperates with the rope core drilling tool to achieve core extraction without lifting the drill. Its advantages are mainly reflected in improving drilling efficiency, reducing labor intensity, and ensuring core quality. The specific details are as follows:
1. Significantly improve drilling efficiency
No drilling for core extraction: Traditional drilling for core extraction requires the entire set of drill rods to be extracted from the hole, while the rope core extraction winch is connected to the inner pipe assembly through a special steel rope (steel wire rope), which can directly extract the inner pipe containing the core from the drill rod to the ground, extract the core, and then return the inner pipe to the bottom of the hole for further drilling. This process saves the time of frequently lifting and lowering the drill rod (which accounts for more than 60% of traditional drilling hours), especially in deep hole (several hundred meters to several kilometers) drilling, the efficiency can be improved by 30% -50%.
Strong continuous drilling capability: The operation of taking and placing the inner pipe is fast (usually taking only 10-20 minutes for a single core extraction), reducing the downtime in the hole, lowering the risks of hole wall collapse, buried drilling, etc., and ensuring the continuity of drilling.
2. Reduce labor intensity and operational risks
Mechanized operation: The winch uses a hydraulic or mechanical transmission system to lift and lower the inner pipe, requiring only 1-2 people to control the winch handle or button during operation, replacing the heavy physical labor of traditional manual lifting of drill rods and greatly reducing the labor intensity of workers.
Reduce in hole accidents: By eliminating the need for frequent lifting and lowering of drill pipes, problems such as pipe bending and thread wear are avoided. At the same time, the safety risks of collisions and falls of drill pipes during lifting are reduced, improving operational safety.
3. Ensure the quality of rock cores and drilling accuracy
High integrity of rock core: The inner tube assembly adopts a closed structure, and the rock core is minimally disturbed during the coring process, which can fully preserve the original geological information (such as rock structure and mineral distribution), especially suitable for geological exploration with high requirements for rock core quality.
Better hole inclination control: reduces the repeated disturbance of the drilling rod to the hole wall, maintains the verticality of the borehole, improves drilling accuracy, and avoids subsequent core extraction difficulties or data deviations caused by hole inclination.
4. Adapt to complex drilling environments
Strong equipment flexibility: The rope core winch has a relatively compact volume and can be adapted to different types of drilling rigs (such as light portable drilling rigs and large crawler drilling rigs). It is suitable for various scenarios such as surface drilling and tunnel drilling, especially in complex mountainous and mining areas where it can still operate stably.
Compatible with multiple geological formations: By replacing different specifications of inner pipes and drill bits, it can adapt to complex geological conditions such as soft rock, hard rock, and fractured formations, meeting diverse exploration needs.
5. Reduce overall costs
Reduce consumables consumption: Reduce the number of times the drill rod is pulled up and down, lower the wear and replacement frequency of the drill rod and drill bit, and save consumables costs.
Shortening the construction period: An efficient coring process can shorten the single hole drilling cycle, indirectly reducing labor, equipment leasing and other time costs, especially in large-scale exploration projects with significant economic benefits.
