Description

A kind of single power source closes control platform device

Technical field：

This utility model belongs to drilling equipment technical field, is related to a kind of single power source closing control platform device, passes through Wall-rock crack development characteristics after detection of coal seam exploitation, research colliery production process coal seam wall-rock crack development characteristics and evolution mechanism Problem.

Background technology：

At present, although colliery is in China's energy-consuming accounting continuous decrease, space of top prominence does not shake, coal The safety problem that resource exploitation is related to remains the Important Problems of China's energy industry safety monitor.Coal seam in recovery process, Due to losing the supporting role in coal seam, goaf overlying top board, underlie base plate and surrounding coal body can be in the work of mine pressure With lower generation unstability, rupture, movement, weight new steady s tate is finally reached.And the crack of surrounding rock failure development, then it is underground current There is the artificial passage of migration in body, such as in South China, during roof and floor water flowing fractured zone will cause overlying strata and floor strata Strong water content is directly entered adopts space；In the Taiyuan Forma-tion coal seam recovery process of North China, base plate water flowing fractured zone is great The thickness of effective water barrier is reduced, causes Water Inrush to take place frequently；The Northwest progressively becomes the weight of coal resources in China exploitation Point region, coal production capacity will account for national first place in recent and future, as northwest Jurassic System Coalfield layer position is new, bury shallow, coal seam The water producing fractures that cause of exploitation cause Quaternary aquifer water to miss, the problems such as thus result in ecology, groundwater environment.To sum up institute State, adopt wall-rock crack, particularly water producing fractures development is focus a series of to Water Inrush, roof water-inrush, water protection mining etc. The Research foundation of problem, and the detection to water flowing fractured zone, then be the emphasis in engineering practice problem and difficult point.

At present, water flowing fractured zone Detection Techniques mainly include physical prospecting field and drilling field, and drilling method be it is most directly perceived, A kind of most practical method, double-end sealing leak detection device are also a kind of dress of detection height of water flowing fractured zone maximally effective at present Put, but in long-term engineering practice, its own has many defects, be particularly the device and must use gas and water source Two kinds of power, (wherein carry out blocking, carry out cranny development detection using water using gas), but most underground site condition This condition is not provided simultaneously with, particularly stops the detection of mining face crack, first mining face crack detection seasonal epidemic pathogens and waterpipe Removed, pipeline during detection, must be set up again；Second, the current recording mode of double-end sealing leak detection device is still Stop watch figures record watermeter flowing rate, and mode is backward and data are inaccurate；3rd, the biography that the water in double-end sealing leak detection device is used Defeated pipeline is drilling rod, must assure that drilling rod is completely embedded with drilling rod and water-tight in detection process, and this state is impossible Exist, some drill pipe sections have leak certainly, be exactly the water leakage situation of observing block section as crack detects, thus greatly Reduce crack detection accuracy；4th, either plugging operations device or water filling device, its design are complex, Pipeline connection is chaotic, and particularly plugging device often results in being split up for air bag, and water filling device Jing often occurs water meter explosion and silt Obstruction.In the case where coal seam is thicker, peephole arranges general longer, and when down-hole detects, drilling rod is typically advanced by rig, is seen During survey, progress is extremely slow, as the steam hose that plugging device is used is located on the outside of drilling rod, therefore in drilling rod progradation Often there is flexible pipe breakage in Jing, cause air bag close, finally can only return again, advance again, remeasure, thus wave Substantial amounts of human and material resources and time are taken.Therefore, in the urgent need to developing a kind of novel, efficient country rock detection system list Power source closes control platform device, and (single power source) accurately measures country rock mining induced fissure development feelings under the limited conditions Condition.

The content of the invention：

Goal of the invention of the present utility model is the shortcoming for overcoming prior art to exist, and seeks design and provides a kind of single-power Control platform device is closed in source, and (single power source) accurately measures country rock mining induced fissure developmental state under the limited conditions, enters And study colliery production process coal seam wall-rock crack development characteristics and evolution mechanism problem.

To achieve these goals, agent structure of the present utility model includes that closed platform inlet union, closed platform go out Mouth joint, closing control platform support, closed system control main valve, first pressure table, backflow stop valve, second pressure table and pressure release Drain valve；Closed platform inlet union, closed platform outlet connection, closed system are installed to control main valve, first pressure table, return Stream stops the pipeline of valve, second pressure table and pressure release drain valve and is placed on closing control platform support, closed platform inlet union One end be connected with the outside underground ventilating pipeline or supply channel for providing enclosed power source, the other end is with closed system control always Valve connects, and the two ends of first pressure table are stopped valve with closed system control main valve and backflow respectively and are connected, for observing closed power The gross pressure in source；Second pressure table stops valve with backflow respectively and pressure release drain valve is connected, and pressure release drain valve is arranged on the downside of pipeline And be connected with closed platform outlet connection, closed platform outlet connection is connected to the flexible pipe that caliber is 10mm, Jing after pressure regulation, voltage stabilizing Enclosed power source is flowed out by closed platform outlet connection.

Single power source closing control platform described in the utility model can both use gas as enclosed power source, it is also possible to make With water as enclosed power source, double pressure gauges that platform is arranged ensure that the pressure in closed process is steady, and be provided with backflow Only valve and relief valve, both energy quick-speed interruption detection process, protect detection instrument without damage.

Compared with prior art, its simple structure is easy to use for this utility model, and parts are light, assembling is quick, into This is low, and control process is stable, accurate, the coal seam country rock mining induced fissure development detection being particularly suitable for during down hole problem.
