Abstract
The invention relates to a coal mining process, in particular to a working face through-cut tunneling construction once-tunneling process, which solves the problems of complicated operation, low efficiency and the like of the existing working face through-cut process. The rectangular cross section tunneling is used for coal mining working face through-cut; a left upper of a coal mining working face is provided with an opening, so that an anchor rod and a steel belt are used for combined supporting, and an anchor rope is used for reinforced supporting; the coal mining working face through-cut construction is performed from the left upper opening of the coal mining working face in a direction towards a left roadway; and a circulation and alternation way is used for construction to complete the whole coal mining working face through-cut engineering. The original twice roadway tunneling through-cut forming mode is merged into the once-tunneling mode for construction; the technical flow process is simplified; the problem of gas management in construction is solved; the process that a roadheader needs to be reversed to a through-cut opening during the roadway tunneling for the second time in the prior art is reduced; and the time required by construction through-cut is greatly reduced.
Description
Technical field
The present invention relates to a kind of coal winning technology, be specially a kind of working face open-off cut eye tunneling construction simultaneous drifting technique.
Background technology
The incisor canal of existing coal-face needs twice one-tenth lane, and distance effective distinguished and admirable instability in air channel when being faced with second time digging laneway in work progress, return air gas probe is difficult to management and controls easy overload alarm, and there is the long distance of fully-mechanized digging machine and fall the construction of machine, repeat the problems such as installation also with various auxiliary equipment.
As schematically shown in Figure 1, with Gushuyuan ore deposit 15# coal 154305 working face open-off cut eye construction technology in detail former construction method is described in detail: 1 site environment and technical condition: 154305 working face open-off cut eyes adopt rectangular cross section, by 1543051 left side openings, adopt anchor pole, steel band combined supporting, and carry out reinforce support with anchor cable, cut an overall length 180.660 meters (in in).2 construction operation programs: to be constructed to 1543052 directions, lane 154305 working face open-off cut eyes by the 1543051 left side in lane openings, first adopt the construction of 4.7m × 2.6m section to cut eye and lead cave 180.660 meters to 1523052 lanes side (array pitch 1.5m, advance of working cycle 3m), afterwards fully-mechanized digging machine is caused incisal guide opening part, adopt section hair wide × hair is high=2.5 × 2.6(rice) to carry out cutting eye brush large, 154305 working face open-off cut eye engineerings of having constructed.
Summary of the invention
The present invention cuts a problem such as complicated operation, inefficiency for technique existence to solve work on hand face, provides a kind of working face open-off cut eye tunneling construction simultaneous drifting technique.
Technical scheme of the present invention is, a kind of working face open-off cut eye tunneling construction simultaneous drifting technique, coal-face is cut eye and is adopted rectangular cross section driving, by coal-face left side opening, adopt anchor pole, steel band combined supporting, and carry out reinforce support with anchor cable, cut eye by left side opening direction, the lane construction to the right coal-face of coal-face, adopt circulation mutually to hocket; First adopt the section of a kind of wide a × high b to construct one to circulate, progress is c; , then adopt the large c of section brush of wide c × high b, form one wide (a+c), high b, progress is c cuts a unit, then adopt the method construction that mutually hockets to complete whole coal-face and cut an engineering.
The present invention and prior art compare: adopt former method to lead after cave excavates, forced air duct air outlet is received and is not more than 8m place to apart from leading cave work plane, cut eye brush large time because forced air duct air outlet is apart from cutting a brush large working area air channel distance, the gas that when brushing large, work plane corner is gushed out not easily dilutable, easy generation gas exceeding limit warning accident, and lead after cave excavates, fully-mechanized digging machine need be caused cave mouth, add dismounting to cut eye and lead cave track, the technique of falling machine; Adopt the method for the invention that twice original digging laneway is formed the mode of cutting eye, the mode merging into simultaneous drifting is constructed, simplify technological process, and solve a difficult problem for gas administration in construction, fully-mechanized digging machine need be fallen machine to the technique of cutting eye mouth when decreasing original second time digging laneway, and avoid to tear open and again follow closely, greatly accelerate the time of constructing and cutting required for eye.
Work of the present invention, adopts to complete from circulation propelling when cutting opening driving and wholely cuts an engineering, the mode of simultaneous drifting.Twice original digging laneway is formed the mode of cutting eye, the mode merging into simultaneous drifting is constructed, simplify technological process, and solve a difficult problem for gas administration in construction, fully-mechanized digging machine need be fallen machine to the technique of cutting eye mouth when decreasing original second time digging laneway, greatly accelerate the time of constructing and cutting required for eye.

Detailed description of the invention
As schematically shown in Figure 2, with Gushuyuan ore deposit 15# coal 154306 working face open-off cut eye construction technology in detail new construction method is described in detail:
1 site environment and technical condition: 154306 working face open-off cut eyes adopt rectangular cross sections, by 1543061 left side openings, adopt anchor pole, steel band combined supporting, and carry out reinforce support with anchor cable, cuts an overall length 180.660 meters (in in).
2 construction operation programs:
To be constructed to 1543062 directions, lane 154306 working face open-off cut eyes by the 1543061 left side in lane openings, adopt circulation mutually to hocket; First adopt wide 4.7m × high 2.6m section to construct one circulate (array pitch 1.5m, advance of working cycle 3m), adopt afterwards section wide × height=2.5 × 2.6(rice) brush large 3m, then the construction that mutually hockets of employing the method completes 154306 working face open-off cut eye engineerings.
Claims (1)
1. a working face open-off cut eye tunneling construction simultaneous drifting technique, it is characterized in that coal-face is cut eye and adopted rectangular cross section driving, by coal-face left side opening, adopt anchor pole, steel band combined supporting, and carry out reinforce support with anchor cable, cut eye by left side opening direction, the lane construction to the right coal-face of coal-face, adopt circulation mutually to hocket; First adopt the section of a kind of wide a × high b to construct one to circulate, progress is c; Then adopt the large c of section brush of wide c × high b, form one wide (a+c), high b, progress is c cuts a unit, then adopt the method construction that mutually hockets to complete whole coal-face and cut an engineering.
