    Abstract
  • A monitoring system of suspension type single hydraulic prop for underground forepoling was introduced, and working principle and design scheme of the system were focused on. The system can realize pressure and bending deformation detection of hydraulic prop, LED warning and wireless data transmission. The experimental result based on a type of hydraulic prop shows that the error between measurement value of the system and the theoretical one is small, which verifies that the system can actually reflect bending deformation degree of suspension type single hydraulic prop when the hydraulic prop suffers different stress from roof and provide accurate data for safety warning of forepoling.
