In mining construction, the use of milling excavators is the key to shortening the construction period and reducing costs. Combining the characteristics of mining rocks with construction needs, mastering the following key points can achieve speed and efficiency improvement, and fully leverage equipment advantages.
Firstly, accurately match the model with the job scenario. According to the hardness of the mining rock layers, select milling excavators that are suitable for torque, and prioritize high torque models for medium hard rock layers to avoid low efficiency caused by small horses pulling large vehicles; Different processes such as tunnel excavation and slope finishing are combined with corresponding milling heads to reduce equipment switching time, achieve multi-purpose use of one machine, and improve overall construction coherence.
Secondly, standardize operational procedures and optimize homework methods. Operators need to be familiar with equipment performance, adopt continuous cutting mode, avoid frequent start stop, and reduce equipment loss and time waste; Control the advance speed and cutting depth during milling excavation, adjust in real-time according to the hardness of the rock layer, maintain a reasonable milling excavation speed for medium rock layers, ensure efficiency and prevent excessive wear of the milling head, while ensuring a smooth milling excavation surface and eliminating the need for secondary trimming processes.
Furthermore, do a good job in daily maintenance and troubleshooting. There is a lot of dust and complex working conditions in mines. Before daily operations, check the milling and excavation head tools, hydraulic system, and replace worn tools in a timely manner to avoid downtime caused by tool damage; Regularly lubricate and maintain the equipment to reduce the occurrence of mechanical failures, ensure the continuous and stable operation of the equipment, and avoid unplanned downtime affecting the project schedule.
Reasonably plan the construction plan and coordinate the allocation of equipment. According to the mining progress, reasonably arrange the operation time of milling and excavation machines, coordinate with loading and transportation equipment, and avoid process disconnection; Optimize the homework route, reduce equipment idle time, make full use of equipment capacity, achieve integrated operation of milling, excavation, discharging, and transportation, and truly achieve the goal of speeding up and increasing efficiency, and reducing construction costs.
