Description
Technical field
The present invention relates to coal mining equipment, specifically a kind of mine drill stem device.
Background technique
In process of coal mining, the coal mine content and gas bearing capacity of different directions are gas control and prevention, and
The important reference of the related fieldss such as coal mine value estimate and exploitation.Due to China Mine Geological complicated condition, and largely
Coal mine has the case where Gas, this also causes gas to become one of the important arch-criminal that China's coal-mine exploits accident, seriously
The raising of the life security and coal production efficiency of coal miner is threatened.Such as gas accident occurs altogether for China's coal-mine in 2005
414, cause more than 2000 people dead.And by 2008, because casualties caused by gas accident drops to 778 people.2010
Year gas accident 126 occurs to rise, causes 593 people dead.And by 2016, national gas accident occurs 59, leads to 348 people
It is dead.For one group of group data while illustrating that gas accident constantly declines, many coal mines are also still faced with serious gas thing
Therefore it threatens.And gas bearing capacity how is accurately measured, it is always the international headache in gas preventing and control field.Accurate Determining gas bearing capacity
Difficult point mainly have a two o'clock: first point is the fixed point acquisition that not can guarantee coal sample, and second point is that the loss amount of gas not can be carried out
Accurately calculate.
Now, most of expert's having focused in the calculating to gas loss amount solution both at home and abroad, leads to
It crosses and establishes a series of model to simulate the process of gas adsorption and parsing, to calculate the loss amount of gas.However, gas
Entire absorption resolving be a complicated physicochemical change, influenced by complicated and diversified environmental condition, in reality
All variables that can not completely simulate in entire change procedure are tested in room.Therefore, none effective method so far
It goes accurately to measure the gas bearing capacity in coal seam.
In China, due to multiple and frequent, domestic many coal minings enterprises of coal mining gas accident in history
Industry all has accumulated a large amount of experience in gas preventing and control countermeasure.Specifically, there are three types of most common, the first is gas
Rig floor is arranged on the surface layer in coal seam in extraction technology, carry out extraction to the gas in mine by drilling equipment.This
In technology, the secondary extraction to exploiting colliery may be implemented, and the utilization rate of coal bed gas can be effectively improved；Secondly,
Extraction is carried out to the coal mine not yet exploited, coal seam itself will not be had an impact, significantly reduce safety accident
Probability；Therefore, this technology is relatively more in external application.Second is layer-through drilling extraction technology, the distribution according to coal seam
Situation carries out successively drilling well-digging to coal seam, then carries out extraction to coal bed gas again.This technology can be improved the effect of drilling well
Rate, but the layer-through drilling extraction technology building time is longer, project amount is big, this also affects the popularization of the technology.The third is
Long drilled holes extraction closes on coal seam technology, i.e., since roof rock, the gas in the coal seam of tunnel is replaced with horizontal drilling,
Then extraction coal bed gas.Effective solution stress concentrates the gas in coal seam, realizes and continuously opens to device in Gas in coal mine
It adopts.But the technology is higher to drilling construction technical requirements in use, therefore is not easy to production and management work
