Description

A kind of comprehensive utilization ratio coal winning technology higher
Technical field
The present invention relates to coal winning technology technical field, a kind of comprehensive utilization ratio coal winning technology higher is specifically referred to.
Background technology
Since 18th century, with the big industry demand growing to the energy, the production capacity of coal increases substantially. The coal annual production of Britain in 1770~1850 years surges to more than 50,000,000 tons from 6,200,000 tons, accounts for Gross World Product at that time 2/3, by 1913, reach 2.92 hundred million tons of all-time high.The U.S. is 2.45 hundred million tons in output of coal in 1900, to nineteen forty-seven Increase in a leap to 6.24 hundred million tons, once kept rank first within a period.The Soviet Union only had 34,500,000 tons in output of coal in 1916, Nearly 1.7 hundred million tons by 1940, No. 1 in the world has been always maintained at since 1958, yield exceeded 700,000,000 tons from 1975. China is to find and use one of earliest country of coal.But before 1949,62,000,000 tons of highests were once reached except nineteen forty-two Outside historical record, general annual production only has 30,000,000 tons or so.After the founding of People's Republic of Chinas in 1949, exploitation, construction Large quantities of new wells, have remodeled and expand original mine, the coal production ability is improved rapidly, the coal of whole nation unified distribution at the beginning of nineteen eighty-three 552, ore deposit, the mining area for producing more than 10,000,000 tons per year has 10, and raw coal output has exceeded 700,000,000 tons.
With the increase of output of coal, the byproduct of coal mining also increases, for example：Mine water, coal bed gas, gangue and coal slime Deng these byproducts can cause environmental pollution in directly placing or being discharged into the Nature.
In progress of coal mining, underground water is contacted with coal seam, rock stratum, adds the movable influence of the mankind, there occurs one The physics of series, chemical and biochemical reaction, thus water quality has significant coal industry feature：Mine water containing suspension Suspension content is significantly larger than surface water, and sensory properties is poor；And the granularity of contained suspension is small, light specific gravity, sinking speed slow, Coagulation effect is poor；Also contain the organic pollutants such as used oil, oil emulsion in mine water.The total ion concentration contained in mine water It is more much higher than general surface water, and be greatly sulfate ion.
The content of the invention
It is an object of the invention to provide a kind of comprehensive utilization ratio coal winning technology higher, can be by the big portion in mine water Divide harmful substance removal, while obtaining the clear water of relative clean, clear water is used for production and living, and be harmful to for original by the coal winning technology Material is converted into utility, is prevented from environmental pollution, and effective environmental protection improves salvage value.
The present invention is achieved through the following technical solutions：
A kind of comprehensive utilization ratio coal winning technology higher, includes raw coal handling process, mine water treatment technique and coal seam Gas disposal technique, mine water treatment technique is as follows：
The first step：Mine water in mine is lifted in reaction tank by elevator pump, and poly- third is added in reaction tank Acrylamide and aluminium polychloride；
Second step：Mine water, polyacrylamide and aluminium polychloride in question response pond enter sedimentation basin after being well mixed Precipitation；
3rd step：Sedimentation basin upper liquid is entered into intermediate pool, then filtering by valveless filtering pool and sterilization pool disappear Poison, uses into underground fire sprinkler equipment for fire sprinkler；
4th step：The sludge of sedimentation basin bottom is entered into sludge-tank, then is set by being arranged outside centrifugal dehydrator dehydration and dry mud Standby carrying, sends into dry mud and stacks field.
By above-mentioned steps, the most of harmful substance in mine water can be removed, while obtaining the clear of relative clean Water, clear water is used for production and living, and original harmful substance is converted into utility by the coal winning technology, is prevented from environment dirty Dye, effective environmental protection improves salvage value.
Further, the coal bed gas handling process is as follows：Coal bed gas is sent into coal gasification apparatus, and in coal gasification apparatus Mixed gas after the completion for the treatment of that coal gasification is abundant, are sent into separation equipment, separation equipment sub-argument by middle addition oxygen, steam and coal Go out gas liquor and tar, residual gas sequentially enters switching equipment and low-temp methanol washes equipment, divide in low-temp methanol washes equipment After separating out sulphur, into methane synthesis device synthesizing methane.Coal bed gas is converted into methane by the technique, for production and living gas, energy It is enough effectively to utilize coal bed gas, turn waste into wealth, prevent coal bed gas from directly discharging the atmosphere pollution for causing, while extracting sulphur, enter one Step removal harmful substance, air conservation.
Further, gas liquor and tar sequentially enter gas liquor and tar separation equipment, phenol reclaimer, recovery ammonia set Standby and waste water biochemical treatment equipment, and tar is isolated in gas liquor and tar separation equipment, reclaimed in phenol reclaimer Crude phenols, liquefied ammonia is isolated in recovery ammonia equipment.Tar, crude phenols and the liquefied ammonia isolated are the important raw material of industry, can be direct For industrial production.
Further, the raw coal handling process is as follows：Raw coal is sub-elected into coal, gangue and coal by wash coaling equipment Mud, coal is deposited in coal yard, and gangue and coal slime are used as construction material, soil filler and fuel used to generate electricity, discarded after generating Thing is used as construction material.The technique makes full use of gangue and coal slime, effectively reduces dust pollution and noxious waste pollution.
Further, fire sprinkler is applied not only to by the water of sterilization pool, is additionally operable to domestic water and outer row., after treatment Water compared with safety and sanitation, and water after treatment is more than fire sprinkler, and unnecessary water can be directly used for domestic water and directly outer row.
The present invention compared with prior art, have the advantage that for：
(1) original harmful substance is converted into utility by the present invention, is prevented from environmental pollution, effective protection ring Border, improves salvage value.
(2) the invention provides the overall treatment to mine water, coal bed gas, gangue and coal slime, can be by the process of mining All products processed, comprehensive utilization ratio is higher.
