Analysis of the Most Complete Stone

Original Title: Analysis of the Most Complete Stone Mining Technology and Equipment in History The most complete stone mining technology and equipment in history For your reference. This article is divided into four sections for you to sort out. The article is long, so you can collect it first. Read patiently, welcome to forward and share! [Types and Elements of Stone Mines] [Deposit development and development transportation method] [Mining process of stone deposit] [Classification of Mining Methods for Stone Mines] [Types and Elements of Stone Mines] I. Types of Stone Mines The types of stone mines include open-pit mining and underground mining. Open-pit mining is divided into hillside open-pit mining, sunken open-pit mining and well mining. Underground mining is divided into cave mining and shaft mining. 1. Open-pit mining: A stone mine in which the overburden and weathered layer on the surface of the stone ore body need to be stripped before mining. An open trench is dug from the ground and a working face is created to extract the block from the working face. According to the topographic conditions of deposit burial, the stripping of the part inside the ore body that cannot become blocks due to the existence of joints,fastest dth hammer, fissures and vein rocks. Rough block: the shape basically meets the specification requirements of the block, but the surface is uneven, with a positive error of more than 3,mining dth bit, and the block stone needs to be shaped. According to the requirements of the Technical Specification for Decorative Stone Open-pit Mines, Mining Drilling Equipment ,Borehole Drill Bits, the comprehensive recovery rate of decorative stone mines should not be less than 50%. Flame cutting machine combined with hand-held rock drill,dhd drill bit, drilling row holes combined with splitting mining method (referred to as burning rock drilling mining method) is the traditional, longest and most widely used granite mining method.
