Abstract
The invention discloses an arrangement method for the double-uphill air return of the mining areas of a mine. In the arrangement method, two groups of a front group coal mining area and a back group coal mining area which have a close distance in a mining level are firstly provided with a main haulage roadway in a united way, the front group coal mining area and the back group coal mining area are respectively provided with a coal-transporting uphill roadway, a track uphill roadway and an air-return uphill roadway, a crossdrift is dug between the air-return uphill roadways of the front group coal mining area and the back group coal mining area, and the air-return uphill roadways of the two mining areas are mutually communicated. Under the condition that the total exploitation quantity of the roadways of the mining areas of the mine is not changed basically, the invention solves the problem of insufficient ventilation quantity, lowers the temperature of the underground mining areas effectively and improves the underground working environment.
Description
Technical field
The present invention relates to the down-hole coal excavation arrangement system, relate in particular to the method for arranging of return aircourse.
Background technology
At present when coal mining multilayer coal, situation is deposited in tax according to the coal seam, usually preceding group of coal exploiting fields that two groups of distances is close and group coal exploiting field, back are united and are arranged a main haulage roadway in a mining level, every layer of coal arranged the exploiting field, and each exploiting field is arranged a fortune coal bord-up, a ginney tunnel and a return air bord-up at least.The coal that is positioned at the upper strata is called preceding group coal, and the coal that is positioned at lower floor is called back group coal.The group coal also can be adopted earlier and afterwards organize coal before also can adopting earlier, also can exploit simultaneously by forward and backward group of coal.
Along with the deepening of the mine degree of depth, ground temperature increases, and the section of original return aircourse seems too small, and flowing resistance is excessive, causes the ventilation deficiency, makes temperature rising in the exploiting field, and operating environment is poor, and the staff easily produces fatigue, influences ordinary production.If strengthen the problem that return air bord-up section solves the ventilation deficiency, will increase the construction volume in tunnel greatly.
Summary of the invention
The objective of the invention is provides a kind of method for arranging of double-uphill air return for solving the problem of above-mentioned mining areas of mine ventilation deficiency.
A kind of method for arranging of double-uphill air return of mining areas of mine: at first in a mining level, main haulage roadway of layout is united with group coal exploiting field, back in two groups of preceding group of close coal exploiting fields of distance, preceding group coal exploiting field and group coal exploiting field, back are respectively arranged a fortune coal bord-up, a ginney tunnel and a return air bord-up respectively, it is characterized in that, with crossdrift of digging between the return air bord-up in preceding group of coal exploiting field and group coal exploiting field, back, two exploiting field return air bord-ups are connected mutually.
When organizing coal before the exploitation, make return aircourse, two exploiting fields return air simultaneously.When exploiting back group coal, the return air bord-up while return air of group coal before also can using.Therefore, exploit preceding group coal or back group coal two return aircoursies while return air arranged side by side are all arranged.
Advantage of the present invention is, under the situation of developing amount always constant substantially (only increasing a developing amount that connects crossdrift), solved the problem of ventilation deficiency in the mining areas of mine tunnel, and the temperature in exploiting field, down-hole is effectively reduced, and improved the underground work environment.
Description of drawings
Fig. 1 is that section of the present invention is arranged schematic diagram, do not draw among the figure fortune coal bord-up and ginney tunnel.
Among the figure: 1-main haulage roadway, 2, the 3-return aircourse, 4-crossdrift.
The specific embodiment
As shown in Figure 1, the present invention at first unites main haulage roadway 1 of layout with two groups of preceding group of close coal exploiting fields of distance with group coal exploiting field, back in a mining level, before group coal exploiting field and group coal exploiting field, back each arrange a fortune coal bord-up, ginney tunnel and return air bord-up 2 and 3 respectively, with crossdrift 4 of digging between return air bord-up 2 and 3, two exploiting field return air bord-ups are connected mutually again.
When organizing coal before the exploitation, make return aircourse, two exploiting fields 2 and 3 return air simultaneously.When exploiting back group coal, 2 while of the return air bord-up return air of group coal before also can using.Therefore, exploit preceding group coal or back group coal two return aircoursies while return air arranged side by side are all arranged.
The bord-up of indication among the present invention, the appellation of the mining type that refers to go up a hill is called go-downhill roadway when going down the hill mining type in the colliery, and this is that those skilled in the art know altogether.So " double-uphill air return " of appellation of the present invention also can be " two go down the hill return air ".
In the technical scheme of the present invention, only described the situation of the preceding group of first exploitation coal, when the group coal of exploitation back, method for arranging as hereinbefore.
Claims (1)
1. the method for arranging of a double-uphill air return of mining areas of mine, it at first unites main haulage roadway of layout with two groups of preceding group of close coal exploiting fields of distance with group coal exploiting field, back in a mining level, preceding group coal exploiting field and group coal exploiting field, back are respectively arranged a fortune coal bord-up, a ginney tunnel and a return air bord-up respectively, it is characterized in that, with crossdrift of digging between the return air bord-up in preceding group of coal exploiting field and group coal exploiting field, back, two exploiting field return air bord-ups are connected mutually.
