Study On The Way Of Preventing Gas Burst In The Process Of Uncovering Coal At The Quan Shuigou Ore

The coal that occupies about 70% of our country energy consumption every time is the important energy in our country. According to authoritative organization predicted, the percentage will still account for about 60%by 2020 and about 50% by 2050. However, as the increase of mining depth, the land structure becomes to be more and more complex, which cause the accident coal and gas outburst of taking place frequently, and the casualties caused by the accident is very serious. So research of coal and gas outburst prevention methods is very urgent in order to ensure the miner's life safety, coal industry's stable and sustainable development and the rapid development of our national economy.This paper chooses the Quan Shuigou ore as research object and analyses coal seam occurrence conditions and characteristic. The Quan Shuigou ore gas's various basic parameters are measured by the experiments in laboratory and field, and using separate source and the forecast method gets the Quan Shuigou ore's coal gas emission. The way of prevention gas burst in the process of coal mining that is usually used now is detailed introduction and compared, finally we choose to make two drilling site to dozen drilling hole as the Quan Shuigou ore's the way of preventing coal and gas outburst. The drilling cuttings desorption index method is used to check the effectiveness of the technology of preventing gas burst. If the technology of preventing gas burst is effective, we will use long-distance blowing to uncover the coal seam. After using the technology of perverting gas burst, the three shimen are uncovered safely. The time of uncovering coal by belt shimen is earlier three days than rail shimen, and a week than returning air shimen. The result of successfully and quickly uncovering coal seam means that the technology of preventing gas burst making two drilling site to dozen drilling hole is viable and effective..
