1.Optimize the selection and configuration of drilling rigs
(1) Select the right drilling rig: Select the right blasting drill according to the geological conditions of the operation. For example, when working in hard rock, a drilling rig with strong adaptability and high power should be selected to increase the drilling speed.
(2) Improve the performance of the drill bit: The drill bit is the key factor in determining the drilling efficiency. Using high-quality drill bits, such as diamond drill bits or carbide drill bits, can effectively improve the working efficiency of the drill rig, reduce wear and increase the drilling speed.
(3) Configure the right power system: Ensure that the power system of the drill rig is powerful enough to provide sufficient drilling pressure and speed. Modern blasting drills are often equipped with high-efficiency hydraulic systems that can provide strong driving force and improve the efficiency of the drill rig.
2.Improve the drilling fluid and spray system
(1) Optimize the drilling fluid: During the blasting drilling process, the drilling fluid plays a role in cooling, lubricating and cleaning the drill bit. Selecting the appropriate drilling fluid can reduce friction, improve the cutting performance of the drill bit, and effectively clean the drill cuttings and prevent blockage.
(2) Regularly check and replace drilling fluid: The quality of drilling fluid gradually decreases with use. Regularly test its viscosity and other properties, and replace and adjust it as needed.
(3) Optimize the spray system: Rationally configure the spray system to ensure that the drilling fluid can continuously and effectively flush the drill bit and remove debris in the hole.
3.Improve the rationality of drilling parameters
(1) Optimize drilling pressure: Too high drilling pressure will cause the drill bit to wear too quickly, while too low drilling pressure will affect the drilling speed. By optimizing drilling pressure, the drill bit can maintain efficient cutting, reduce wear, and thus improve drilling efficiency.
(2) Adjust the rotation speed: During drilling, an appropriate rotation speed can improve the cutting effect of the drill bit. Too high a rotation speed may cause excessive wear of the drill bit, while too low a rotation speed may affect the drilling speed. Reasonable selection of rotation speed can extend the service life of the drill bit while ensuring efficiency.
(3) Reasonable selection of footage: Too fast a footage may cause instability of the hole wall, while too slow a footage may affect efficiency. By optimizing the footage rate, the overall efficiency can be improved.
4.Strengthen the maintenance and care of drilling rigs
(1) Regularly check the drilling rig equipment: Regularly conduct a comprehensive inspection of the drilling rig, including the power system, hydraulic system, transmission device, etc., to promptly detect and deal with potential faults and avoid downtime or efficiency loss caused by equipment failure.
(2) Replace worn parts: Such as drill bits, seals, etc., regularly check and replace worn parts in a timely manner to ensure that the equipment is always in the best working condition.
(3) Optimize the lubrication system: Ensure that the key components of the drilling rig (such as the hydraulic system, transmission system, etc.) are fully lubricated to reduce friction losses and improve efficiency.
5.Improve operator skills and work processes
(1) Train operators: Skilled operators can better adjust the working parameters of the drilling rig, flexibly respond to geological changes, and improve the working efficiency of the drilling rig. Therefore, regular training of operators and improving their operating skills is the key to improving efficiency.
(2) Real-time monitoring and adjustment: Modern blasting rigs are usually equipped with an automated monitoring system that can monitor the working status of the drilling rig in real time. Through real-time monitoring, operators can quickly adjust parameters according to the working conditions, avoid invalid operations, and improve work efficiency.
6.Reduce non-productive time
(1) Optimize operation scheduling: Rationally arrange the working time and rest time of the drilling rig to avoid long downtime and reduce non-productive time.
(2) Quick drill change: When the drill bit is worn, quickly replace the drill bit and ensure that the spare drill bit is in good condition to avoid downtime caused by drill bit problems.
7.Technological innovation and automation
Adopt intelligent drilling rigs: With the development of technology, many blasting drilling rigs have begun to be equipped with intelligent control systems, which can automatically adjust drilling parameters (such as drilling pressure, speed, etc.) to adapt to different geological conditions and improve drilling efficiency.
Introduce remote monitoring and diagnosis system: Through the remote monitoring system, the working status of the drilling rig can be grasped in real time, problems can be discovered and adjusted in time, and the impact of failures on efficiency can be avoided.
8.Optimize blasting design
(1) Scientific blasting design: Reasonable blasting design can reduce resistance during drilling. By reducing the volume of blasted rock, adjusting the blasting intensity, and reasonably arranging the blasting time, the burden of the drilling rig can be reduced and the drilling efficiency can be improved.
(2) Accurate blasting location: Avoid over-blasting or under-blasting, accurately control the location of the blasting point, and reduce unnecessary waste and drilling difficulties.
