Abstract
The invention relates to the field of underground fully-mechanized excavation for a coal mine, in particular to a fully-mechanized excavating roadway cross-operation construction process. The fully-mechanized excavating roadway cross-operation construction process comprises the following steps that: I, after a second underground roadway is communicated with a normally constructed first roadway, the left and right peripheral sides of a scraper-trough conveyer of a first roadway coal output system support plate beam parts at the crossed part of the two roadways, and the plate beam height of the plate beam parts meets the requirement that a second machine unit can pass through the scraper-trough conveyer; and II, when the first roadway is in a support state, the second machine unit carries out coal cutting above the scraper-trough conveyer through the plate beam parts, and a carrying part conveys coal; after the construction completion, the second machine unit retreats back to one side of the scraper-trough conveyer through the plate beam parts for supporting the second roadway, a first machine unit starts to cut the coal, and the scraper-trough conveyer conveys the coal; the operation is repeated and cycled in such a way, after a space sufficient to accommodate the second machine unit exists in the other side of the scraper-trough conveyer, the plate beam parts are lengthened, and the second machine unit drags and hoists the carrying part to pass through the plate beam parts and rides on the scraper-trough conveyer; the second machine unit continuously cuts the coal, the carrying part continuously conveys the coal, and after the carrying part completely passes through the scraper-trough conveyer, the second roadway utilizes the first roadway coal output system.
Description
Technical field
The present invention relates to combine pick field under coal mine, specifically a kind of combining dug tunnel cross-operation construction technology.
Background technology
At present, after a tunnel under coal mine and the roadway linking of another normal construction, be equipped with scraper-trough conveyer equipment of producing coal system etc. due to another tunnel, the unit, the supporting part that have stopped this tunnel cannot pass through the scraper-trough conveyer in another tunnel, so this tunnel can not continue to tunnel forward, must adopt big gun to dig or stop driving, needing to wait for after producing coal system is changed in another tunnel and can dig by continuation machine, all impacts to some extent aspect time and drilling depth like this.
Summary of the invention
When the present invention combines pick tunnel cross-operation in order to solve two tunnels can be independent of each other, the problem of normal machine pick, a kind of comprehensive pick tunnel cross-operation construction technology is provided.
The present invention is achieved by the following technical solutions: combine pick tunnel cross-operation construction technology, the steps include:
I. after the first roadway linking of the second tunnel, down-hole and normal construction, in the scraper-trough conveyer left and right of the first tunnel producing coal system of two tunnel infalls, all sides support plate-girder portion, and the plate-girder height of plate-girder portion meets the second unit and passes through scraper-trough conveyer;
II. the first tunnel is in the time of supporting state, and the second unit carries out coal cutting above scraper-trough conveyer by plate-girder portion, supporting part fortune coal; After having constructed, the second unit is refunded scraper-trough conveyer one side by plate-girder portion, and supporting is carried out in the second tunnel, and the first unit starts to carry out coal cutting, scraper-trough conveyer fortune coal; So iterative cycles, until scraper-trough conveyer opposite side has behind the space of being large enough to hold the second unit, plate-girder portion lengthens, the second unit towing supporting part is by plate-girder portion and ride on scraper-trough conveyer; The second unit continues coal cutting, and supporting part continues fortune coal, until supporting part passes through scraper-trough conveyer completely, the second tunnel utilizes the producing coal system in the first tunnel.
Comprehensive pick tunnel cross-operation construction technology of the present invention, reasonable in design, two lane intersecting machine picks are independent of each other while construction, on driving time and digging footage, reach largest optimization, have obtained huge economic benefit and social benefit.

Detailed description of the invention
Combine pick tunnel cross-operation construction technology, the steps include:
I. after the second tunnel 2, down-hole connects with the first tunnel 1 of normal construction, support plate-girder portion 4 in the scraper-trough conveyer 3 left and right week sides of the first tunnel 1 producing coal system of two tunnel infalls, the plate-girder height of plate-girder portion 4 meets the second unit 5 by scraper-trough conveyer 3;
II. the first tunnel 1 is in the time of supporting state, and the second unit 5 carries out coal cutting above scraper-trough conveyer 3 by plate-girder portion 4, and supporting part 6 is transported coal; After having constructed, the second unit 5 is refunded scraper-trough conveyer 3 one sides by plate-girder portion 4, and supporting is carried out in the second tunnel 2, and the first unit 7 starts to carry out coal cutting, and scraper-trough conveyer 3 is transported coal; So iterative cycles, until scraper-trough conveyer 3 opposite sides have behind the space of being large enough to hold the second unit 5, plate-girder portion 4 lengthens, the second unit 5 towing supporting parts 6 are by plate-girder portion 4 and ride on scraper-trough conveyer 3; The second unit 5 continues coal cutting, and supporting part 6 continues fortune coal, until supporting part 6 utilizes the producing coal system in the first tunnel 1 completely by scraper-trough conveyer 3, the second tunnels 2.
