On July 30, good news came from Duanwang Mine of Duanwang Coal Industry, with a single-day commercial coal output of 13,500 tons, a new high in single-day commercial coal output in recent years. Since July, the mine's daily commercial coal output has stabilized at the level of 10,000 tons, laying the foundation for completing the task target in the third quarter and boosting confidence.
In July, they firmly grasped the golden period of stable attendance of personnel, took the initiative to attack, and further optimized the adjustment of the mining surface layer to ensure the recovery of top coal to the greatest extent and improve the output of raw coal, especially in the second fully mechanized mining area to overcome the difficulties of the 150507 working face encountering structures, faults and collapse columns, and chose a new cutting eye to avoid the structural area, ensuring that the coal was cut 7 times a day. Under the condition of ensuring the stability of gas, the first fully mechanized mining area compresses the maintenance time, prolongs the operating rate, and keeps the coal cutting at more than 5 knives per day, achieving a steady increase in output.
In order to ensure that the production indicators are completed as planned, they decompose the production indicators to the production team every day, and then the production team combines the actual situation of the unit to refine and quantify the production indicators and responsibilities to each team. "More tasks are completed, safety and quality are high, there are fewer hidden dangers on site, less points are deducted, and more money is equaled" has formed a consensus in all district teams and teams of the whole mine, fully mobilized the enthusiasm of employees for safe production, and effectively formed an incentive mechanism for the interaction of output, efficiency and income.
In the face of the actual situation of long transportation lanes, many equipment, large coal transportation pressure, and serious wear and tear of structural equipment on the working face, they planned ahead and actively took corresponding measures to increase the adjustment of the support to ensure that the support state was intact. At the same time, the shearer driver is strictly required to control the speed of coal cutting, and cooperate with coal cutting and coal transportation to reduce the impact of transportation and ensure production. After the maintenance team completes the maintenance work, it is required to cut coal with heavy load, and redeal the problems that occur in the process of heavy load operation, so as to effectively ensure the normal operation of the equipment and lay a solid foundation for stable and high yield.
At the same time, the coal washing plant of the mine innovatively implements the "equipment contracting responsibility system", inspects, maintains and maintains the equipment frequently, and carries out hidden danger investigation, system implementation, on-site compliance and walking inspections in an orderly manner to ensure that the equipment is intact, and the equipment integrity rate reaches more than 98%, ensuring that the amount of raw coal washing is stable and rising.
