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 rock drilling tools 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 platform 2-Safety Platform 3-Cleaning platform 4-Transport channel α β-final slope angle GF-Lower final line of open pit H-Final mining depth of open pit AB-Upper final boundary line of open pit ABGHF-Final state of open pit 1 Bench When stone is mined in the open pit the ore body to be mined is usually divided into horizontal layers with a certain thickness and mined layer by layer from top to bottom mining dth bit When two or more horizontal slices are mined at the same time a certain advance distance shall be kept between the upper and lower slices A step shape is formed in the space during the mining process and at the end of the mining process These step-like working surfaces are called steps The bench is the basic element of the stone open pit and also the unit of the independent quarry operation 2 Working platform horizontal part of each step 3 Safety platform the stope boundary is reserved to ensure the safety of the lower production platform and the stability of the slope 4 Cleaning platform one cleaning platform shall be set every 2-3 safety platforms 5 Transportation channel transportation road between the ground and each horizontal layer [Deposit development and development transportation method]
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 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 deposit joint occurrence development degree orebody shape …Flame Cutting Machine IV Advantages and disadvantages High efficiency (15 ~ 25 ㎡/H) flexibility large cutting depth (up to 10 m) large cutting area smooth cutting surface not affected by season and climate High noise (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 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 Copyright notice If it involves copyright issues please contact us to delete it!
