Research on fast Construction Technology of east roadway in HuaHeng Coal Mine

摘要

By analyzing various factors which influence and constraint roadway construction speed in huaheng coal mine, some improved technical measures about fast construction are introduced, such as improve blasting technology, choose appropriate rock breaking equipment and improve the fast construction supporting facilities, select the right support patterns and scientific construction organization management. Take east roadway in huaheng coal mine as example, there are three key aspects: the method of mucking and haulage, drilling and blasting techniques and supporting technology. In solving the problem of loading and transport, some mechanized equipments such as LW150C bucket loader, SSD(B)20 shuttle mining car and CMJ17A full-hydraulic excavating jumbo are used, and the mechanized organization such as loading, transfer, transport and unloading is innovated. By improving bolt installation construction technology and optimizing construction management to achieve simultaneously operating of multiple procedure, increase drilling speed and shorten mucking time, which improved the roadway excavation speed and security significantly.
