Transportation in Mines

-
Day to day the mines are growing...
In earlier days there were labours employed for transportation purposes but now the many machineries are employed to increase production. Now we will discuss different types of haulage system..

Rope haulage, Belt conveyor and chain conveyor are mode of transportation in Mines.
In coal mines the use of locomotives are on small scale, but it's a standard practise in underground multifarious mines.

Below are the methods of transportation

1.Rope Haulage
Mainly the rope haulage is divided in to four types. We will discuss one by one...

A.Direct Rope Haulage:- In this haulage system, the tubs are attached with rope at both end. The empty tub travel down wards by their own weight and due to gradient.
As cleared above that there is no need of power from engine to downward travelling.
This system can be employed for branch road as tubs travel by their own weight.
• Gradient:- 1 in 10
• Speed :- 8 to 12 km/h
• Branch Road deviation angle :- 40°
• Only one track required.

Drawbacks of this system
• High power requires for the starting of          load tubs.
• Maintenance of tracks should be standard.
•  Derailment causes highly damage.
• For speed control, the braking system is        employed.

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
