The morning shift and the middle shift moved 10 shields per shift at the longwall recovery of F31311 LW. This was the best record on moving the shields in one shift of this coal mine. The mining grid guaranteed the safety and speed of the shield moving by its protection on the roof.


It’s known that work was tough and time was tight for the recovery of the F31311 LW and its completion would directly affect the next arrangement of the pit. At this crucial moment, the team was aware of the production severity. Focusing on and considering the production succession, the team devoted to the longwall recovery rapidly which mobilized the initiative of th workers.

During the longwall recovery, the team thought ahead and organized several meetings to advance the work. Aiming at the situation of the job-site, they discussed and proposed the optimized construction skeme. Based on the experience from the previous longwall recovery and according to the requirement of the coal mine, they improved 5 aspects of the mining grid technology. Additionally, they changed the application method and reasonably used the mechines and equipments. In the longwall recovery, the mining grid was strong and good in integrity which reduced the falling of the gaugue and roof caving.

The mechnized mining team is expecting to finish the longwall moves within 22 days in order to start the installation of next longwall as quick as possible adn guarantee the production succession of the next half year.
