As the core equipment in mining, the standardized use of mining milling excavators directly affects the mining progress, operational safety, and equipment lifespan. Combining with the complex working conditions of mines, the following techniques can help them better exert their efficiency and achieve a dual improvement in safety and efficiency.
Adequate preparation is necessary in the early stage. Before starting the homework, it is necessary to survey the work area, clarify the rock hardness, geological structure, and surrounding obstacles, and select suitable milling and excavation heads according to the working conditions to avoid low efficiency or equipment damage caused by equipment mismatch with the working conditions. At the same time, inspect all components of the equipment, with a focus on checking the hydraulic system, milling head tools, connecting bolts, etc., to ensure that there is no looseness or leakage, and that there is sufficient lubricating oil and hydraulic oil, laying the foundation for safe operation.
Standardized operation is key. When operating, it is necessary to follow the principle of “gradually progressing from shallow to deep”, avoid milling and excavating too deep at once, and prevent equipment overload or rock collapse from injuring people. Control the milling speed and feed rate, adjust flexibly according to the hardness of the rock, slow down the speed and reduce the feed rate for hard rocks, and speed up appropriately for soft rock layers to ensure smooth milling and reduce the workload of secondary processing. At the same time, avoid horizontal hard scraping and forced milling to prevent tool wear and equipment failure.
Daily maintenance is essential. Due to the large amount of dust and harsh working conditions in mines, it is necessary to regularly clean the surface and internal dust of equipment, check the wear of cutting tools, and replace severely worn tools in a timely manner to avoid affecting milling and excavation efficiency. Regularly maintain the hydraulic system and lubrication system, replace filter elements and oil, check seals to prevent impurities from entering the system and causing malfunctions. Check the equipment in a timely manner after shutdown, clean and protect it, and avoid equipment corrosion.
In addition, it is necessary to strengthen the training of operators, so that they can proficiently master the equipment operation specifications and emergency response methods, and eliminate illegal operations. Reasonably arrange homework shifts, avoid prolonged continuous operation of equipment, reserve maintenance time, and extend the service life of equipment. Following the above points can fully leverage the advantages of mining milling excavators, improve mining efficiency, reduce safety risks and equipment maintenance costs.
