Safer mine hoisting with conveyance position and load monitoring

“…Existing hoist load monitoring techniques are mainly obtained indirectly by monitoring parts such as wire ropes, tension balancing devices, motors and reels [13,14]. Beus and Iverson [15] designed a new tension sensor to detect the state of the wire rope and thus determine the load of the hoist. Jiang et al [16] calculated the wire rope tension by measuring the period of the transverse vibration wave of the wire rope and then obtained the hoist load.…”

A hoist load monitoring method based on machine vision technology is proposed in this paper to address the frequent overloading accidents of mine hoists and the low safety and reliability of existing contact load monitoring technologies. The depth image of the skip undergoes time domain and spatial bilateral filtering algorithms for noise reduction, followed by conditional filtering and downsampling algorithms to remove redundant point cloud data. Point cloud recognition, extraction, segmentation, and alignment algorithms are then applied to quickly generate a skip point cloud model. A surface reconstruction optimization process combining greedy projection triangulation algorithm and void repair algorithm is proposed to obtain a smooth and complete sealing of the skip. The closed surface model volume is calculated using VTK volume function. Based on single-rope winding hoist, a load visual monitoring system is constructed for relevant experimental research. Results show that this method can accurately measure the loaded coal volume with a relative error range of 0.05%~4.13%, meeting practical application requirements while providing an effective way for non-contact accurate measurement of hoist loads in mines.

The article describes the adjustable electric drive of skip hoisting installations of the mining enterprise. A simulation model of this object has been developed in the MatLab software package using the Simulink environment. The lift cycle was simulated using a five-period motion tachogram and graphs of dependencies of the following variables on time were obtained: the movement speed of the skip, the armature current and the motor torque. The simulation results showed that this simulation model corresponds to the actual technological process and allows further research on the operation of skip hoists.
