The invention discloses a device and method for longitudinally automatic laying and networking of bottom plates in layered mining of thick coal seams. The device includes a first hydraulic support and a second hydraulic support arranged side by side. The first rear seat and the second rear seat are respectively provided. The first hydraulic support and the second hydraulic support are respectively equipped with a first middle mesh roll and a second middle mesh roll, and the first middle mesh roll and the second middle mesh roll The first net and the second net are respectively wound on the net rolls in the frame, and an automatic laying and networking mechanism is installed between the first hydraulic support and the second hydraulic support. The automatic laying and networking mechanism includes a net roll laying unit and a pushing unit And the networking unit, the inter-shelf net roll laying unit is used to install or spread the wound third net, and the push unit is connected with the inter-shelf net roll laying unit. The invention realizes the automatic paving and networking of the layered mining floor of the thick coal seam, reduces the workload of underground workers, improves the networking efficiency, and has great operability and practicability.
Description
technical field [0001] The invention relates to the technical field of layered mining of thick coal seams, in particular to a device and method for longitudinally automatic laying and networking of bottom plates for layered mining of thick coal seams. Background technique [0002] The so-called thick coal seam refers to the coal seam above 3.5m in underground mining and 10m in open pit mining. my country's thick coal seam production accounts for about 45% of the total raw coal production. It is a country with large reserves of thick coal seams and a large mining country of thick coal seams. Thick coal seam is the main coal seam for high-yield and high-efficiency mining in my country's coal mines. Due to its thick coal seam, there are many coal mining methods to choose from. At present, there are generally three types of thick coal seam mining techniques in my country, namely, layered mining, large mining height and full height mining at one time, and top-coal caving mining....
