3 Methods of Coal Mining

Published

on

Surface mining is used for an estimated 40% of coal production. Used machinery equipment can be used to extract coal. Extracting coal is less expensive if it’s found near the surface. Once coal is extracted, the topsoil is then replaced and native trees and vegetation is planted to restore the original condition. There are three different types of surface mining: contour, strip, and mountaintop removal mining.

1- Contour Mining: Contour Mining is most commonly used in areas that have steep or rolling terrain. It involves digging the earth above the coal line, or coal seam, along the contours of the hilly terrain. This method can be dangerous because it may cause landslides and erosion problems.

2- Strip Mining: Strip Mining usually occurs on flat terrain. The earth is dug up in long cuts or strips until the coal seam is exposed. After the strip has been drilled and blasted and all the coal has been removed, a new strip is created right next to it and the process continues.

3- Mountaintop Removal Mining: Mountaintop Removal Mining involves using a combination of Contour Mining and Strip Mining. The mountaintops are removed to expose the coal beneath and the coal is extracted.

Underground Mining Methods

If the coal seams are too deep underground, then deep underground mining is necessary. Deep underground mining methods include Continuous, Longwall, Blast, Retreat Mining and Shortwall Mining.

o Continuous Mining: A machine that has a large rotating steel drum with tungsten carbide teeth scrapes coal from the seam. Conveyors are used to transport the removed coal. About 5 tons of coal can be mined per minute. Accounts for about 45% of underground coal production.

o Longwall Mining: A sophisticated machine that has a rotating drum that mechanically moves back and forth along the seam. Loosened coal falls on the pan line which takes the coal to the conveyor belt. Accounts for about 50% of coal production.

o Blast: An older mining method that uses dynamite and explosives to break away the coal seam. Accounts for less than 5% of coal production.

o Retreat Mining: One of the most dangerous coal mining methods. Pillars are used to hold up the mine roof as coal is extracted. The pillars collapse as miners retreat.

o Shortwall Mining: Similar to longwall mining. Uses a continuous mining machine with moveable roof supports. The machine shears coal panels about 200 feet wide and half a mile long.

El Salvador’s Chivo And Bitcoin Adoption In Mindblowing Facts And Stats

Published

on

Chivo, a goat over a mountain

Why didn’t we thought of measuring Chivo and Bitcoin adoption this way? Cero anecdotal evidence. Only facts, numbers, and reports from wherever we can get them. What do we know about the Chivo Wallet’s Lightning node? What apps besides the government wallet are the Salvadorans using? Are they happy with them? Investor and blogger Kevin Rooke has a fresh take on El Salvador’s Bitcoin adoption and we’re here to summarize it. 

“I wanted a deeper understanding of how real people in El Salvador are interacting with Bitcoin, so I went off in search of other success metrics.”

However, since “the Lightning Network is private by design,” it’s hard to accurately measure “payment volumes and the flow of funds between various wallets and exchanges.” So, what did Kevin Rooke do? He looked everywhere else for hard data about Chivo and Bitcoin adoption. Let’s explore what he found.

The Chivo Ecosystem Is Growing Fast

To measure the Chivo wallet’s adoption, Rooke used the official information provided by President Bukele. Not ideal, but not uncommon either. It’s easier to get info about the Chivo Lightning node because you can check all the public info here. But wait, why is the Salvadorean government running a Lightning node?

“Just like every other participant on Bitcoin’s Lightning Network, Chivo runs a Lightning node. Since Chivo is a custodial wallet, all Lightning payments that Chivo users send to and from other Lightning wallets will transfer liquidity to and from Chivo’s node.”

Through those sources, what did the author find out about the Chivo ecosystem?

  • At the moment, “Chivo’s node has 12.7 BTC of public capacity.” Which is 1,269,941,898 sats.
  • The Chivo node “ranks 83rd among public Lightning nodes.” 
  • At the time of writing, it’s connected to 58 other channels, but this number changes daily.
  • Back to the iOS App Store and Google Play Store, the Chivo wallet remains at the top of the popularity list, “beating all the most popular social media apps like WhatsApp, TikTok, and Instagram.
  • O bet you haven’t thought about this one, “By onboarding over 1.6 million users in just two weeks, Chivo is likely the most popular Lightning Network app in the world today.

What About The Other Bitcoin Apps? Are They Popular In El Salvador?

Ok, granted. El Salvador’s government incentivizes the downloading of the Chivo wallet app with $30. That has to move the needle. However, when it comes to all the other Bitcoin apps, such an incentive doesn’t exist. How are they measuring up to other financial apps?

This infographic says it all:

  • Salvadorans are already showing strong preference for Bitcoin apps over banking and remittance apps on a national scale,” as the graphic shows.
  • To put it in numbers, “9 and 13 of the top 20 apps on the respective app stores” are Bitcoin apps. And Chivo is at number one.
  • Most of El Salvador’s banks and payment processors have user ratings of 2-4 stars,” that’s the traditional banking system for you.
  •  On the other hand, “Bitcoin related apps have user ratings of 3-5 stars.” Even though it’s still early, the facts are the facts. It should be noted that the Chivo app is at the lower end of that spectrum.

Besides that, Kevin Rooke identified a truth that might be obvious to some, but has to be said:

“The millions of Salvadorans that have already been onboarded to the Lightning Network aren’t Silicon Valley nerds or early tech enthusiasts. They’re regular people that are making a conscious choice to use the Lightning Network because it saves them time and money.”

And they don’t have to use the Chivo ecosystem if they don’t want to. That’s a fact.
