Abstract: In order to improve the construction efficiency of hole for water exploration and drainage in coal mine roadway heading face, a rapid and successful hole drilling rig with twin boom, narrow body, flexible movement, fast fixing body and adjusting angular is developed, which can also be alternated with heading machine. Three key parts including gyrator, feeding mechanism and luffing mechanism are studied. The test shows that the drilling rig is designed reasonably and can meet the requirements of rapid and successful hole for water exploration and drainage in heading face, which provides a reliable equipment guarantee for safe and high efficient heading in coal mine.
