Prototype of temporary mechanized mine roadway support of the dog headings

摘要

Technology of the dog heading driving with use of roadheaders or explosive material has been described in the present study.Difficulties occurring during dog heading driving, particularly those related with the support installing, have been presented.Constructional solutions of different mechanized mine roadway supports, including their advantages and disadvantages, have been presented.Based on the executed analysis of the mine dog heading driving, including construction of mechanized roadway supports, a new concept of temporary mechanized roadway support has been developed and its technical parameters have been cited.
