In surface mining the ground covering the coal seam the overburden is first removed to expose the coal seam for extraction The elements of a surface mining operation are 1 topsoil removal and storage for later use 2 drilling and blasting the strata overlying the coal seam 3 loading and transporting this fragmented overburden material called spoil 4 drilling and blasting the
Use line diagrams or scattergrams if both the independent and dependent variables are numeric; use bar graphs if only the dependent variable is numeric; and use bar graphs or pie charts for proportions Different Types of Graphs and Different Types of Charts In data analysis there are several different types of graphs and charts

The rapid rise of electric vehicles EVs in India requires more energy to power these vehicles In addition the transport sector emits greenhouse gases especially carbon dioxide CO2
Coal mining Underground mining In underground coal mining the working environment is completely enclosed by the geologic medium which consists of the coal seam and the overlying and underlying strata Access to the coal seam is gained by suitable openings from the surface and a network of roadways driven in the seam then facilitates the installation of
Pie chart representing different sources of methane emissions in the united states Which production processes lead to the release of carbon dioxide during coal mining A chart is a visual representation of data information or concepts There are many different types of charts each suited for different purposes and types of data
3 Pie chart examples Example 1 Basic pie chart Figure 2 shows a pie chart for the classes of passengers on the Titanic The goal is to show that over half of the passengers had third class tickets least expensive The other passengers are nearly evenly split between first and second class tickets
1 Introduction The Global Coal Mine Tracker GCMT provides information about the major coal mines in the world every operating mine producing 3 million tons per year or greater and every proposed mine with a capacity of 1 million tons per year or greater the GCMT tracks 1513 coal mines 1085 operating coal mines and 485 proposed coal mines in 59

According to the data in the pie chart coal produced % of energy in 1995 and increased slightly by more than 1% in 2005 Similarly energy manufactured by gas comprised of % in 1995 rising slightly upto % The two pie charts represents different types of energy produced between 1995 and 2005 in France Overall coal gas
The continuous miner cutter CMC sleeve is an integral part of the mining tools including the boxes and picks It is designed to allow free rotation of the pick in its bore while cutting the coal
Coal Formation of Coal Types of Coal Peat Lignite Bituminous Coal & Anthracite Coal Carbon content in different types of coal Importance of each type Coal Also called black gold Found in sedimentary strata [layers of soil] Contains carbon volatile matter moisture and ash [in some cases Sulphur and phosphorous]
The World Coal Association explains that the quality of coal is largely determined by the type of vegetation the coal originated from; the coal s depth of burial
Although the United States has the vast coal resource described in the previous chapter perhaps as much as 4 trillion tons the key issue for policy makers is the amount of coal that is economically is not a fixed quantity but depends on the geological resource the market price and the cost of mining The particular characteristics of the coal mining industry
Second is to construct knowledge graph relying on the data of the coal mining field For example Xu et al [12] constructed a knowledge graph in coal mine gas extraction domain Peng et al [13] modeled coal mine safety aware concepts and
