大直径气动潜孔锤钻进实验平台设计与研究OA

The experimental platform of large-diameter pneumatic down-the-hole hammer can simulate drilling and rescue scenarios in mining accidents to provide test support for the rapid drilling of large-diameter rescue holes.The platform developed has functions such as automatic feeding and pressurization,automatic rotation control,and multi-media circulation control,which can conduct full-scale drilling experiments and meet the requirements of large diameter,multifunctional,multi process,multi-media and multi parameter testing.This paper introduces the main system components of the experimental platform,as well as the design and verification calculations of the pressurization system,rotation system,and bench foundation.Based on this experimental platform,drilling experiments were conducted to simulate the construction of mine rescue channels,verify the effectiveness and reliability of large-diameter pneumatic down-the-hole hammers and other equipment,and provide test conditions for improving the efficiency and safety of mine rescue.
