Study on the development of the Medium-scale Gas Explosion Integrated Testing System

摘要

Based on the characteristics of gas explosion in coal mines, the medium-scale gas explosion integrated testing system is developed. The integrated testing system is comprised of shock tube, testing section, explosion venting capsule, measuring instruments system, and other auxiliary equipments. The measuring instruments system can detect parameters of explosions and flow fields by the study of coupling relation between explosion and flow field. The synchronous control mechanism is employed to ensure parameters being simultaneously detected. The testing section can be adjusted to matching different testing requirements. Results of testing are useful to the prevention of gas explosion, emergency response and accident investigation.
