Studies [2, 3] have shown that fly ash, furnace slag and desulfurization gypsum can be compounded to form gelled materials with a certain strength under given conditions.
Experimental Raw materials and chemical characterization The 42.5 R cement used was supplied by Yangluo cement plant in Wuhan; desulfurization residues (flue gas desulfurization gypsum, fly ash and furnace slag) were supplied by a thermal power plant in Wuhan.

Relationship Study between Bolt Shape and Anchor Performance Shuo RENa, Jianxing WUb, Jianzhong LIc Coal Mining and Design Department, Tiandi Science and Technology Co., Ltd., Beijing 10013, China aemail:rsmyfriend@126.com, bemail:wujianxing123@163.com,cemail:952674989@qq.com Keywords: Bolt Shape; Anchor Performance; Rib Spacing; Rib Height; Drawing Force Abstract.
With the popularity of bolt support and bolt itself has become the indispensable support materials in coal mines, so the bolt's research is become particularly important.
As for the design of bolt rib height, only need to reach a certain value, which not only save materials but also reduce the installation resistance
