Mine Gases-The physiological Effects 1

-

1.Carbon Monoxide
The Carbon Monoxide is very poisonous gas and it's affinity towards the Haemoglobin is nearly 300times greater than Oxygen.Even if it is present in small quantity reduces the absorption of Oxygen for the blood.It may be named as sweet poison because without the carbon Monoxide Detector no one can identify it's presence.
It's increase in percentage can cause....
At following percentage effects can be identified as
0.02-Headache,discomfort and may collapse within 45 to 2 hours.
0.12-Palpitations after 10 minutes of work or 30 minutes at rest.
0.2-Unconsciousness after 10 minutes at work or 30 minutes at rest.
0.5-1.0(Death within 10-15 minutes).
*Sources- Spontaneous combustion, Incomplete combustion etc.

2.Carbon Dioxide
The sources of Carbon Dioxide are oxidation of Coal, Decay of timber, IC engines etc.
The Carbon Dioxide when dissolve in water forms Carbolic acid.It would cause mild irritation because of the presence of water (eyes, Nose , throat) and in respiratory system due formation of Carbolic acid.

Physiological Effects:
10%- Burning sensation on Mucous membrane.
5.8%-Breathing rate Double

3.Oxygen
It is most important gas to survive but only 25% of inhaled oxygen is used by lungs and rest come-out.
Source:- Ventilation air
Physiological Effects:-At
17%-Faster and deeper breathing.
15%-Dizziness, buzzing in ear, faster heart bear.
13%-Loss of consciousness on long exposure.
9%-Fainting and unconsciousness.
7%-Life endangered.
6%-Convulsive movement, Death.

Detection:- It can be detected by flame safety lamp.But now the electronic gadgets are also available for detection.

4.Nitrogen:- It is act as inert gas as it has no adverse effects on human as long as percentage of oxygen is sufficient.

Secondary Blasting Technique

In this post we will deal about the Definition of Secondary Blasting and types of Secondary Blasting . Some other Blasting are also available you can read about that. So let's start... Definition of Secondary Blasting The technique used to blast the boulders to achieve the fragmentation is called secondary blasting. This blasting is done to get the rocks which can be easily handled. Why and how to do secondary blasting? Why secondary blasting? We does secondary, in case when the primary blasting don't give fragmentation of rock which can be easily handled. The secondary blasting is followed after the primary blasting. How to do secondary blasting? To do secondary blasting we have to follow some methods which will give us batter resultant. These are here 1. Plaster shooting or Mud Capping.. As name indicates mud capping, the primer cartridge is place at top of Boulder and covered with mud. The blasting is done from the safe place by electric detonator

Bord and Pillar Method

Bord and Pillar Method of mining involves in the formation of roadways and the development of Mines. The first stage of working of Bord and Pillar Method is Called Development. In the development stage parallel roads are driven nearly at right angle to the first set. These roads are also use to join the separated coal blocks. The network of roads regularly increases as development of the mine. The second stage of working of Board and Pillar Method  of mining is called Depillaring. The Depillaring can be understood by It's name(De-Pillaring). In Depillaring the working involves in the extraction of coal from the Pillars. These are two stages of this mining method. The another name of Bord and Pillar method is "Pillar and Stall". For the application of Bord and Pillar Method there are some conditions to be full filled. Conditions are.... •The thickness of seam seam should be more than 1.5m. •There is less amount of dirt bands present in seams. •Se

Shaft Sinking

Q. What is shaft? Ans. :- It is a vertical or inclined entry made to touch seams. The word shaft is used for underground mining entrance. Q. Why shaft? Ans.:- The shaft is excavated after getting approval to mine the mineral bed by underground method of mining. Simple View of Working Shaft Shape of Shaft Generally the shaft are of circular in shape but in some mines it is of rectangular in shape. The circular shafts are best because they resist heavy side pressure and offers least rubbing surface area for ventilation. Bricking and concreting job are easy and diameter of these shaft may be varies from 4.2mts to 6.7mts. ◆The shaft sinking process is costliest and time taking process. So it is necessary to drill pilot hole within the radius of 50m of main shaft which has to be drill. This pilot hole give us an idea about the rock and how we have to encounter those problem which will we face during shaft thinking. From this we will get a data about                      1
