I thought this thread was dead.
tell me diff b/w open cast mining and deep shaft mining.
gonna be alive again, for i know 2 other ppl taking em this time
Open-Cast Mining is applied when the mineral seam is close to the surface or is exposed towards the top. Excavators and mining machinery is used to extract the mineral from the open ground, leaving a large hole in the ground. Coal is mined through this way, sometimes.
Deep Mining is applied when the minerals are located deep in the ground. Shaft Mining is a specific type of Deep mining, in which a vertical shaft is dug into the ground and the minerals are extracted that way. It is an expensive method, and is also very dangerous as underground there are harmful gases that can cause explosions. In case of a disaster it will be difficult to escape, as compared to if the miner was outside. It is also more time-consuming that open-cast mining. Minerals are extracted vertically upwards.
try to do it this way that u mention a diff in one sentence about both the ways. see you mentioned the financial and the "dangerous thingy" diff in the shaft mining but not in opencast. eeach and every of ur points should be diff and distinct, and clearly mentioned, or perhaps described too if the marks are more.
well if we see the points u mentioned are...
1. depth of coal seams
2. visual pollution.
3. finance
4. ease
5. time consumption
my additional points...
1. more transporting proceedure is there in deep mining than in open cast.
2. management of opencast is easy due to landfill method.
3. air and land pollution
Deep mining does not result in air and land pollution?
"less" air and land poll. comparatively v less!
Yeah, open-cast mining is directly exposed to the air, that is why more air pollution.
Thought i got an A still im not satisfied as my paper went good but phir bhi Allah ka shukar guzar hoon sirf suspicious hoon kay what went wrong.What Grade did you guys get?
I got a B. I am happy, as i only did 2 years of pastpapers.
What did you get?as for those who gave EM very few got an A and i have still not come across someone who got an A*
Thank God, got an A*!
Go for a recheck if you think you could do better!
How about a retake?Go for a recheck if you think you could do better!
Not worth it, go for another subject.How about a retake?
World history is one difficult subject. I prepared sociology in just one month and ended up with an A*.I am thinking to go for an extra subject in the May 2014 session with the other six science subjects. I have short listed two of them, History World affairs and sociology. Which one is better? Which is more likely to yield an A or A*? I have got six days to decide! Your suggestions?
