Abstract

The invention discloses a roof bolter lapping control method and control system. The method comprises the steps that when a roof bolter moves to a target position of a current roadway, image information, collected by a camera, of a last installed mesh and an anchor rod tray of the mesh is obtained, wherein the camera is installed on the roof bolter; a position of the anchor rod tray of the last installed mesh in a world coordinate system is obtained according to the image information; according to the position of the anchor rod tray of the last installed mesh in the world coordinate system, installation position information of a current to-be-installed mesh is determined; and the roof bolter is controlled to install the current to-be-installed mesh according to the installation position information of the current to-be-installed mesh. According to the method, an automation degree of coal mine underground anchor protection operation can be improved, manual interference is reduced, and therefore the labor cost is reduced, and the operation efficiency and the operation safety are improved.

Description

technical field [0001] The present application relates to the technical field of anchoring and protection in coal mines, in particular to a control method and control system for laying nets of a rock bolt rig. Background technique [0002] With the expansion of the mine mining range, the mining depth continues to increase, and the mining conditions are becoming more and more difficult, especially in unfavorable rock formations such as high stress, plastic deformation, easily weathered rock formations, broken rock masses, poor stability of rock masses, and poor cementation. excavation and support. After the roadway is excavated, the stress in the surrounding rock around the roadway will be readjusted. If effective protection is not carried out in time, the integrity of the surrounding rock will be damaged, and even the surrounding rock will collapse. [0003] In the related art, it is usually the staff to use the coal mine bolter to fix the mesh on the top and side of the ro...
