First, the pit exploration project 1. Surface pit exploration project Soil stripping (BT) Detecting tank (TC) Shallow well (QJ) (exploring shaft): <30m, the section is rectangular, and support is required when the surrounding rock is easy to collapse. Horizontal ç¡: The surface has an exit flat, <30m, the local shape is strongly cut, and when the ore body is steeply inclined, the horizontal raft is more convenient than the shallow well. 2. Underground pit exploration project (heavy mountain project) Dapingyu: Horizontal tunnel with large surface area (large) >30m Shaft: vertical tunnel with exits on the surface Inclined well: An inclined tunnel with an exit for use as a transport Shimen, Chuanmai: horizontal tunnel without exit, vertical ore body trend. Piercing: the part of the ore body; Shimen: the part of the surrounding rock Stone alley, along the vein: there is no horizontal exit tunnel directly exiting, along the direction of the ore body, the part that is not excavated in the ore body is called Shixiang Patio, dark well: vertical tunnel without direct exit Uphill, downhill: inclined tunnel without direct exit Galacto-Oligosaccharide 90% Powder Galacto-oligosaccharides are made up of plant sugars linked in chains. They are found naturally in dairy products, beans, and certain root vegetables. People use galacto-oligosaccharides as prebiotics. Prebiotics act as food for "good" bacteria in the intestine. Don't confuse prebiotics with probiotics such as lactobacillus, bifidobacteria, and saccharomyces, which are live organisms that are good for health.
