Abstract:
Surrounding rock control of deep soft rock roadway has been a major problem plagued the development of coal mines. Through a large study of supporting theory and technology in deep soft rock roadway, scholars at home and abroad have made a lot of research results. Bolt-grouting technology is the organic combination of bolting and grouting supporting, fully embodies the advantages of grouting and anchoring. Based on the mechanical study of bolt-grouting, we analyzed the types and characteristics of bolting and grout, and then introduced the construction technology and precautions of grouting bolting installation and grouting. Finally, we prospected the research field of bolt-grouting support technology in the future.
