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 se requirements before the mining of the deposit, so as to expose the mineable parts; (3) Internal stripping: the stripping of the part inside the ore body that cannot become blocks due to the existence of joints,mining dth bit, fissures and vein rocks. (4) Stripping ratio: refers to the ratio of the amount of earth and stone stripped to the volume sing requirements of decorative plates. 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 drill bit, and the block stone needs to be shaped. Metering block: the actual metered volume of the block after inspection. It is the actual onsider the construction of a dregs yard with sufficient capacity, which is a necessary preparation for continued production and safe production. Attention should be paid to the protection of resources, the protection of the environment, the comprehensive utilization and the improvement of efficiency. According to the requirements of the Technical Specification for Decorative Stone Open-pit Mines, Mining Drilling Equipment ,DHD Drill bit, the comprehensive recovery rate of decorative stone mines should not be less than 50%. [Classification of Mining Methods for Stone Mines] I. Mining method: Splitting, blasting, cutting, burning, etc. II. Selection basis of mining method: 1. Geological conditions of the depo(100 ~ 120 db), high dust, high fuel consumption, high cost (200 ~ 250 yuan/) and high labor intensity, so it must be combined with other mining methods. Flame cutting machine combined with hand-held rock drill,dth drill bits, 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.
