Description
Technical field
The present invention relates to release extinction technical field in colliery, and in particular to a kind of colliery outburst elimination method of the micro- Protective Coal Seam of wire cutting, is particularly suited for the gas control of the larger single coal seam reservoirs of thickness.
Background technology
China's major part mining area deformation coal comparative development, the coal seam in its region has the features such as ature of coal is soft, gas permeability of coal seam is poor, high methane content, and the gas control of single thicker coal seam reservoirs and coal-bed gas exploitation become generally acknowledged global problem.China's gas control and coal-bed gas exploitation are directed to different coal seam reservoirs and define different production techniques at present.For primary structure coal, when permeability is higher, mainly adopt ground extraction mode；And it is directed to multiple seam, how after the exploitation protective layer release by the way of the extraction of down-hole；For coal seam thickness less single construction coal, frequently with the mode such as extraction after underground fracture or the direct extraction of down-hole drilling；For single " three is soft " coal seam that coal seam thickness is larger, how using extraction after the punching release of Di Chou lane.
In a word, current gas control and Coal-seam Gas Recovery Technologies mainly include following two means：One is to reduce reservoir pressure, cause desorption of mash gas, seepage flow output in the presence of pressure reduction, as ground drilling drainage and step-down gas producing technology and down-hole drilling negative pressure draw out methane technology, but tradition is soft, hypotonic in Coal Quality from the straight well of ground extraction gas and horizontal well and the region of high methane can not effectively large area distressing mining anti-reflection；Another is by disturbance original pressure-bearing coal seam, manufactures Stress Release space, so that coal mesopore crack is increased on a large scale; reduce adsorption gas pressure-bearing; expand gas porous flow output passage, promote gas fast desorption, such as pressure-relief outburst-prevention measure in the layer such as protective coat extracted technology and hydraulic loose.Protective coat extracted technology is one of maximally effective region protrusion-dispelling technology, but it is limited by geological conditions, is generally used for the mine of coal seam group mining, and the coal seam larger to single coal bed and interlamellar spacing is not suitable for.The coal seam larger to single coal bed and interlamellar spacing, though the hydraulic loose carrying out in this coal seam is the anti-reflection outburst prevention measures of release in a kind of layer, serve certain effect in hyposmosis coal body, but in the process of implementation, often exist gas exceeding limit frequently, easily cause the problems such as human-induced projects it is impossible to carry out regional release；Digging laneway in country rock, the pressure release extinction being carried out by layer-through drilling sluicing coal dust, extinction effectiveness comparison is good, but it is great to there is quantities, high cost, problem long in time limit.
Particular for the single construction coal seam reservoirs that thickness is larger; current coal seam reservoirs release extinction technology and Coal-seam Gas Recovery Technologies all do not obtain good effect; simultaneously with the increase of coal seam buried depth; technical difficulty for gas control and coal-bed gas exploitation is increasing; the ton coal treatment cost of coal-bed gas exploitation enterprise continues to increase, need badly searching low cost, can scale, the gas control of automatization and coal bed methane exploring method.
Content of the invention
It is an object of the invention to provide a kind of colliery release outburst elimination method of the micro- Protective Coal Seam of wire cutting, micro- Protective Coal Seam is cut in coal seam reservoirs by closed loop linear profile of tooth cutting belt, reaches coal seam reservoirs release extinction to solve coal mine gas distinct issues.
In order to solve the above problems, the present invention is achieved through the following technical solutions：
A kind of colliery release outburst elimination method of the described micro- Protective Coal Seam of wire cutting, including power set and closed loop linear profile of tooth cutting belt, lay guide-track groove in coal mine work area crossheading, packaged type device is installed in upper crossheading and the guide-track groove of lower crossheading simultaneously, packaged type device moves along guide-track groove, power set are individually fixed on movable fixture, by cutting eye, linear for closed loop profile of tooth cutting belt are installed on two power set.
A kind of colliery release outburst elimination method of the described micro- Protective Coal Seam of wire cutting, mainly includes the following steps that：
（1）Correct position in crossheading installs coal conveyer device respectively；
（2）Start power set, closed loop linear profile of tooth cutting belt presses circulating rotation clockwise or counterclockwise, power set and closed loop linear profile of tooth cutting belt slowly move along crossheading simultaneously, thus closed loop linear profile of tooth cutting belt cuts two micro- Protective Coal Seams of formation in this coal seam；
（3）During cutting this coal seam, the coal dust being produced by dissection is carried to appointed place by being arranged at the conveying arrangement of crossheading to closed loop linear profile of tooth cutting belt respectively.
As preferred, vertically crossheading needs synchronization for power set and closed loop linear profile of tooth cutting belt, and translational speed is by this coal bed texture and gas bearing conditional decision.
Beneficial effects of the present invention are as follows：
A kind of colliery release outburst elimination method of the micro- Protective Coal Seam of wire cutting of the present invention, by way of by the rotation of closed loop linear profile of tooth cutting belt, in this coal seam, cutting forms multiple micro- Protective Coal Seams, disturbance Coal Pore Structure, reduces coal seam pressure, reaches the purpose of coal seam reservoirs release extinction.Cut this coal seam in the present invention and form the equipment configuration of micro- Protective Coal Seam and be simple and convenient to operate, compared with other release outburst elimination methods, the method increase production efficiency, can achieve unmanned Automated condtrol in cutting process simultaneously, greatly reduce the potential safety hazard being likely to result in due to anthropic factor.
