Description
Technical field
The present invention relates to the coal mining method, relate in particular to highly gassy mine Duo Xiang coal wall and arrange the exploitation method of implementing, being specially the many lanes of a kind of high gas does not have the coal pillar mining method.
Background technology
According to condition of coal seam occurrence and gas situation such as gush out, in possessing the mine of selecting employing longwell comprehensive mechanized coal mining method, on the arrangement form of work plane, all adopt many lanes to arrange, the advantage that mainly contains following several respects is arranged in many lanes: (1) adopts many lanes work plane arrangement, flowing resistance is little, face air volume is big, wind gas-removing ability is big, and the ability of dilution gas is big, helps the continuous production of work plane; (2) the tailentry side mostly is the roadway arrangement form of " advances twice " or " advances a time ", and the exhaust ventilation that the upper corner place has formed makes upper corner distinguished and admirable to the motion of goaf direction, the methane accumulation that has solved face upper corner angle effectively; (3) the many lanes of work plane are arranged, except that solve ventilating, again for equipment, the material of work plane, personnel are transported to work plane as early as possible that condition is provided, and have reduced operating personnel's labour intensity, reduce the installation and the repair time of work plane, guaranteed the safety in production of work plane; (4) two of the tailentry side return airways, the tunnel that can be used as next work plane is multiplexing.Owing to have many-sided advantage, the especially advantage aspect gas control, in the roadway workface of current highly gassy mine is arranged, become the first-selection that work plane is arranged.
The assign a work arrangement of face of many lanes, adopt " three advance twice " five lane arrangements mostly, for providing air quantity, equipment, material and personnel, fully-mechanized mining working guarantees, for work plane has been created good production operation environment, but, existing arrangement exists many problems, mainly shows following several respects: (1) coal column stays to be established greatly, and cause serious waste of resources: (2) two return aircoursies stay the multiplexing cost in lane big; (3) stay the lane maintenance time long, the auxiliary expenses height; (4) potential safety hazard is many: the large-mining-height working surface mining height is big, be the twice of common layering fully-mechanized mining working mining height, fltting speed is general to combine three times that adopt soon, and mining pressure manifests and is multiplied, accidents such as anchor cable fracture, wall caving, roof fall happen occasionally, and the difficulty of safety management strengthens day by day.
For many years, people have carried out a large amount of research and exploration aspect no coal pillar mining, obtained effect preferably.As mining area, German Rule DSK company, the coal plough work plane is implemented the no coal pillar mining history of existing more than ten years, the Lushui River peace is encircled energy group Wang Zhuan colliery for another example, adopt full anchor pole roadway support to implement the exploitation of narrow coal column (8m) caving coal full-seam mining, achieve success, and formed fixing exploitation arrangement, apply in this group company.
Summary of the invention
The present invention is unreasonable in order to solve existing highly gassy mine Duo Xiang coal wall layout, causes the problem that cost is big, potential safety hazard is many, and provides the many lanes of a kind of high gas not have the coal pillar mining method.
The present invention is by realizing by the following technical solutions:
The many lanes of high gas do not have the coal pillar mining method, are to arrange main fortune system, auxilliary fortune system, ventilation system in the coal wall, and wherein main fortune system comprises the belt crossheading that is opened in the work plane downside and is opened in the concentrated adhesive tape lane at work plane middle part; Auxilliary fortune system comprise be opened in work plane up and down both sides the air intake crossheading and be opened in the assistant conveyance lane at work plane middle part; Ventilation system comprises the air intake crossheading that is opened in the work plane both sides, be opened in the air return way of work plane upside, with the concentrated return airway that is opened in the work plane middle part, concentrate return airway to communicate with air return way, wherein also offer the n connection roadway in a side of concentrating return airway near work plane by the air return way mouth; Stay between near the belt crossheading in goaf and adjacent work plane goaf and establish narrow coal column L.
The present invention adopts the method for arranging of four lanes " three advance one time ", and concentrated return airway is opened in the middle part of work plane, and the distinguished and admirable air return way mouth through work plane of both sides enters concentrated return airway; Work plane adopts the middle part air return method, has cancelled the difficulty that the management of working surface tail upper corner gas brings; All there is the assistant conveyance lane work plane both sides, adopt the railless free-wheeled vehicle transportation, improved assistant conveyance efficient, have guaranteed equipment, material, personnel's transportation, have alleviated labour intensity; Implement method for arranging of the present invention, need adjust,, change into jumping and adopt organizational form by original order mining to organism of production.
Described n connection roadway is provided with the adjusting air regulator, there is a spot of wind directly to enter concentrated return airway through this, to dilute the gas density of concentrating in the return airway, by the air quantity of this connection roadway, can regulate according to the gas density in work plane and the return airway, to guarantee that gas in work plane and the return airway is all within the scope of " safety regulations in coal mine ", except that this connection roadway, all the other connection roadways are equipped with airtight, along with the work plane forward impelling, open one by one.
Described belt crossheading can be opened in edge, last work plane goaf, concentrates the return side lane to be arranged in the downside of work plane.
Described narrow coal column L also can be opened between the air intake crossheading and adjacent work plane goaf of work plane upside.
Compared with prior art, the present invention has the following advantages:
(1) adopts four lanes " three advance a time " to arrange, reduced loss of coal pillar, played with five lanes and arranged identical ventilation effect;
(2) compare with the five lanes face order mining of assigning a work, implement to jump the organism of production of the formula of adopting,, significantly reduced maintenance workload and the hidden danger of staying the lane to bring though each work plane has increased a tunnel relatively, cost of production reduces greatly, and it is secure to keep the safety in production;
(3) reduce the wasting of resources, realize clean exploitation, green exploitation realizes resource rational utilization and sustainable development, is the direction of coal industry development.
