Must learn mining method

1. This is the standard diagram of the comprehensive mining method for the layout of transportation drift in the vein.
the small piece you refer to in the thick line is the funnel. If you look over the mining design manual, the funnel also belongs to the bottom pillar. The irregular point pillar in the center of the ore block is generally estimated by the rock drillers because they think the ore is poor there
this drawing is a plan. For the standard drawing of mining method of gently inclined orebody, generally only plan and section drawings are made.
except for gently inclined orebody, the rest are generally in front view, top view and bottom view Side view of this sequence
------------------------------------------------------------------ --
in addition, the map you sent is accurate within the vein, OK, close your eyes, according to the design of the middle section of 40m or 50m, drive a roadway along the vein at a certain height, which is the 1-transport roadway on the map, Then dig a way up the mountain at a certain position. For example, it's on the leftmost side of your map. Then, parallel to the transportation roadway, the bottom pulling roadway is g 6-8m up the mountain. Well, two working faces are formed. Mining continues at the end of the mountain, and the bottom pulling roadway breaks through. Right, mining is ahead of mining! Then, ah, sequential mining, it's what you see in the picture

however, this picture is used in the past and used in artificial mining. Nobody uses it anymore. Why can't the proction capacity go up
OK, let's look at the picture,
1. The electric harrow nest is on one side of the transportation roadway, the harrow bucket is on the other side of the transportation roadway, and the steel rope crosses the transportation roadway, which will definitely affect other operations in the roadway
2. The comprehensive method is applicable to the ore body with dip angle less than 30. If it is arranged as shown in the figure, the height difference between the floor height of the transportation roadway and the funnel mouth is relatively small, and it can barely install a wooden funnel to load ore into the car. However, looking at the things in the figure, I think that the transportation roadway is running on a two wheeled wooden frame car, which manually takes the stpan to load ore
3. The efficiency is extremely low when the funnel spacing is 8m and the ore is loaded at multiple points
4. In general, the height of the middle section of a metal mine is more than 40m. If it is 40m, then two rooms on the map can be arranged on one middle section. I don't believe you can try it in CAD^_^< br />_________________________________________________________________
in addition, this is the picture in the old book. If it's your textbook, I despise your teachers. I'm irresponsible and teach students what I learned half a century ago<

for the sake of my hard work in typing so many words, let's have a look
in addition, if you have problems in this area, you can post to me in the mining engineering post bar. I read the post every day
good luck!!!

2. The popularity of defi is not a flash in the pan. Since 2018, the ecology of defi has begun to take shape, but it is difficult for defi to form a large scale e to security problems. From the birth of bitcoin to being endowed with value, digital currency has its own financial attribute, so the first field of blockchain landing must be the financial field. For defi, it is a "secondary finance" based on the valuable consensus of digital currency
since 2020, liquidity mining has ignited defi. As the leading project in the field of defi, compound has launched its own governance token comp, and uniswap is the "initiator". On the one hand, liquidity mining is blooming everywhere, on the other hand, we can see the potential of defi which has been growing for a long time. On the one hand, defi assigns the financial attributes of digital currency, on the other hand, defi is closely connected with various fields of blockchain, such as mining<

for bitcoin Kingdom, which is committed to coordinating, helping, integrating and implementing world BTC resources, funds and policies, solving BTC investment and financing difficulties, electricity consumption and other problems, and promoting the common development of the instry, its system integrates defi. Bit Kingdom uses a multi factor model to study the smart contract, collateral and liquidity risk, and the model itself uses the combination of data outside the public chain and on the chain to assess the risk, so as to improve the security of its decentralized finance as much as possible. At the same time, it abstracts and encapsulates its defi business molarized, and outputs it as SDK and API
for any resource in bitcoin mining system, bitkingdom is involved, especially in the field of mining machinery. In view of the current "shortage of high-quality second-hand mining machinery resources", "mining machinery detection lack of professional process", "second-hand mining machinery trading difficulties", "market pricing and trading lack of standards" and other problems, bit kingdom creates a second-hand mining machinery platform and provides professional mining machinery detection technology to one-stop hosting service. Bitkingdom also introces the digital currency assistant management of kbtc, which enables the buyer and the seller to negotiate the transaction according to the currency function of kbtc (system native token), so as to ensure that users can easily obtain fair and affordable prices from the price mechanism, and carry out the development and upgrading of the project under the guidance of the defi financial model

kbtc, as the original token in bit Kingdom system, plays an important role. Kbtc can attract a large number of users to settle in and pay attention to, and help build kbtc's own traffic pool in the early stage. When there are more and more holders of kbtc, kbtc has monetary function. This means that kbtc can play a more and more important role in "second-hand mining machine trading" and "mining machine computing power trusteeship" as currency. As a deflationary currency, kbtc will become more and more valuable. So for kbtc, it represents the theme of bit Kingdom, and also represents the value
on September 22, 2020, kbtc Tongzheng launched kg trading platform. And on the 22nd at 14:00 p.m. to open the coin charging, Trading (kbtc / usdt) and withdrawal function at 18:00 p.m. The theme of kg trading platform is highly similar to that of bit Kingdom, that is, they are committed to mining ecology and defi finance.

6. Copper mines are generally found in all maps before grade 5 to grade 20. Tin mines are on the map of grade 15 to grade 25, iron ores are on the map of grade 20 to grade 40, then miyin is on the map of grade 40 to grade 50, and sayin is on the map of grade 50 to grade 60. Finally, it is the map of Outland

7. Master. Do you want to make money or improve yourself first
if you want to upgrade, use enchantment and jewelry.
PS: my pastor studies tailoring and engineering. He doesn't say that if you study engineering, you must learn mining. You can buy this kind of collection.

8. Guess from low-level area to high-level area

the collection class is very easy to practice. You can pick it when you see it. Don't be afraid of trouble. In this way, when your level is full, the collection is also full

but it is not recommended to learn medicine and mining together, because only one detection can be opened at a time. If we detect the mineral, we can't detect the medicine

9. If you like PVP, you should learn mining + engineering
if you like PVE, you should pursue high DPS, jewelry + tailor
if you don't like playing g, you should pick medicine + mining
if you like to save time, tailor +
enchant
