Description
Technical field
The utility model relates to a kind of coal mining facility, specifically a kind of facility for mining pressed coal below pipeline.
Background technology
" three times " pressure coal exploitation be the major issue merited attention always, according to incompletely statistics, current China only coal mine under the unified-allocation system mine main " three times " pressure coal just reach 137.9 hundred million t, wherein build down 94.68 hundred million t, account for 69% of stagnation pressure coal amount.Along with carrying out of national West-East National Gas Transmission Project, inevitably produce the situation that coal field crossed by a lot of oil and gas pipeline, and along with the exploitation of mining area underground coal resource, will there is serious potential safety hazard in these pipelines.Once the surface subsidence caused due to coal mining causes serious destruction to pipeline, very large impact will be caused on the environment etc. of the energy of country and locality.Press the exploitation of coal below pipeline, current mainly taking implements resettlement to pipeline, and cost is high, and the cycle is long how simply, fast, effectively, complete below pipeline and press the exploitation of coal to be a great problem.
Summary of the invention
The utility model object is to provide a kind of facility for mining pressed coal below pipeline, and this facility is with low cost, can complete the exploitation of pressing coal below pipeline when guaranteeing pipeline safety.
To achieve these goals, a kind of facility for mining pressed coal below pipeline, comprises support pier basis, support pier, suspention main rope and hoist cable; Described support pier basis instrument is needing the two ends of the pipeline protected; two, one end; arrange in pipeline bilateral symmetry; support pier is arranged on two support pier bases; support pier is arranged on support pier basis; arrange suspention main rope between two support piers, suspention main rope suspends some hoist cables in midair, pipeline is suspended on suspention main rope by hoist cable.
The utility model can affect the dynamic deformation that shallow embedding gas transmission ground pipeline produces according to during exploitation of coal resources; suspension bridge overhead pipe is adopted to protect shallow embedding ground gas transmission line, thus the coal resources held up under adopting conventional mining type can exploit out pipeline.Suspension bridge erection is simple, and critical piece can reuse; After subsidence is stable, suspension bridge removes, because pipeline self has certain tensile properties, there will be no burst distortion, generally without the need to support of banketing, operation is comparatively simple; The cost of the whole coal mining process protection pipeline of the method, less than 10% of prior art, has been saved a large amount of coal resources, has been had high economic benefit.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, a kind of facility for mining pressed coal below pipeline of the utility model, comprises support pier basis 1, support pier 2, suspention main rope 3 and hoist cable 4; Described support pier basis 1 is arranged on the two ends of the pipeline 5 needing protection; two, one end; arrange in pipeline 5 bilateral symmetry; support pier 2 is arranged on two support pier bases 1; support pier 2 is arranged on support pier basis 1; arrange suspention main rope 3 between two support piers 2, suspention main rope 3 suspends some hoist cables 4 in midair, pipeline 5 is suspended on suspention main rope 3 by hoist cable 4.
The utility model can affect the dynamic deformation that shallow embedding gas transmission ground pipeline produces according to during exploitation of coal resources; suspension bridge overhead pipe is adopted to protect shallow embedding ground gas transmission line, thus the coal resources held up under adopting conventional mining type can exploit out pipeline.Suspension bridge erection is simple, and critical piece can reuse; After subsidence is stable, suspension bridge removes, because pipeline self has certain tensile properties, there will be no burst distortion, generally without the need to support of banketing, operation is comparatively simple; The cost of the whole coal mining process protection pipeline of the method, less than 10% of prior art, has been saved a large amount of coal resources, has been had high economic benefit.
Further, for strengthening the steadiness of support pier 2, the utility model also comprises oblique pull cable wire 6 and anchorage 7, and anchorage 7 is arranged on two side positions of pipeline 5 two ends pipeline extended line 8, and oblique pull cable wire 6 one end connects anchorage 7, and the other end is connected with the top of support pier 2.
Further again, regulate for convenience of oblique pull cable wire 6, tensioning apparatus 9 is also set in the above.
Further, be protection pipeline 5, avoid it to be lifted rear local location pressurized excessive and damage, the utility model also comprises base for supporting pipeline 10, and base for supporting pipeline 10 is connected with hoist cable 4 lower end.Sling pipeline 5 time, because itself and base for supporting pipeline 10 contact area are comparatively large, local is born pressure and is diminished, so not easily suffer damage.
Further again, described base for supporting pipeline 10 comprises collet 101 and upper cover 102, and described collet 101 and upper cover 102 are arranged respectively the groove 103 for settling pipeline, collet 101 is connected by bolt 104 with upper cover 102, upper cover 102 arranges hanger 105, and pipeline 5 of slinging like this is not only convenient but also firm.
Further again, described groove 103 arranges cushion course 106, avoids pipeline 5 firmly contact with base for supporting pipeline 10 and damage pipeline.
Further, regulate for convenience of hoist cable 4, tensioning apparatus is set thereon.
Further, described hoist cable 4 and oblique pull cable wire 6 arrange stretching force detecting apparatus, can pulling force situation suffered by Real-Time Monitoring hoist cable 4 and oblique pull cable wire 6, judge that whether whole facility accepts even, adjusts in time.
Further, described hoist cable 4 is suspended on suspention main rope 3 by ground tackle 12, cord clip 13 and high-strength bolt 14, more firmly.
