It covers not only roof control, but also rib control, floor control, pillar design, shield design, overburden failures and subsidence. In the past three decades, ground control has made a tremendous advancement and many case studies have demonstrated its important role in the daily mining operations. However, there are plenty of room for improvements. This paper discusses the research needs in 12 subject areas including research approach, rock property, geology, computer modeling, in-situ stresses, roof bolting, coal pillars, field instrumentation,failures, surface subsidence, shield supports and coal bumps.展开更多

From angles of folk embroidery patterns modelling characteristics are analyzed: include strong decorative and practical; the integrity of the vivid and concise; symbolic connotation deeply; simple random nature; handed down from generation to generation program. Discusses the forming characteristic of folk embroidery modelling is not an accidental phenomenon of art, but has a profound folk custom, economy, religion, and history of aesthetics, with typical regional culture characteristics. The research of folk embroidery in the status of folk art is of great significance. In the future, we will combine more literature review to optimize our current research and broaden the research boundary.展开更多
