Recommendations are put forward for achieving a risk balance between mineral resource estimates and slope design.

Based on the high slope engineering of Guangzhou Skeet & Trapshooting Training Centre,some of the key technique problems of the high slope designing are discussed;and the reinforced design of the high slope is introduced.

It discusses the slope design,sustaining projects and formation of the fill and so on according to landforms,environment,as well as rock\'s features.

earthwork volume,on top of that,the gradient and slope length restriction in design criterion are used to obtain rational and economic longitudinal slope design.

This paper introduces the quality requirement of constraction of surfac water-proof room surface slope designing,mortar trentment paving and the requirements of quality control of each procedure are discussed,at the same time corresponding water-proof treatment methods are proposed for detail parts to ensure construction quality.

This paper deals with features of water-proof PVC-roll-roofing used in roof construction, the methods of roofing slope designing, mortar float-coat and paving.
