Description

Coal-seam high-pressure pulsating water hammer water-infusion device
Technical field
the utility model relates to a kind of water filling device, is especially applicable to coal seam, the coal-seam high-pressure pulsating water hammer water-infusion device of the difficult injecting layer that particularly gas permeability is very poor.
Background technology
along with in the process of coal mining, the degree intensification extremely using mechanization to complete, the dust concentration produced when working surface coal mining machine coal cutting and development machine driving is increasing, and the dust harzard of underground coal mine is day by day serious, and some even reaches 10g/m 3 , serious pollutes operating environment, and workers with long time works under being in this environment and very easily suffers from professional pneumoconiosis, in addition, also easily causes coal and non-coal to explode.Therefore, effectively dust must be administered in the recovery process in colliery, to reduce dust concentration.And in China's " safety regulations in coal mine ", also having regulation, mechanical coal mining work plane must take coal-bed flooding.The principle of this water filling control dust is: after water filling, and the primary coal dust in Wetting Coal makes it lose the ability of flying upward and changes coal body mechanical property.The principle of water filling control gas explosion is: gas pressure is large and in coal seam that gas permeability is very little, often coal and gas prominent is there is under ground pressure and gas pressure acting in conjunction, coal-bed flooding enters hole, crack encloses the passage of adsorption gas desorb, prevent the release of gas, make gas can not manifest its pressure energy, so the energy produced when just reducing gas release, decrease the possibility of gas broken coal.And traditional static pressure water filling belongs to constant pressure water filling, the method is adopted to have very large drawback, one: injection flow will extend with water injection time and reduce gradually; Because along with the increase of water injection time, wetted perimeter increases, and permeation pathway is elongated, thus adds osmotic resistance, causes flow to decline.Its two, coal is after water is moistening, and some porous dehiscence gaps are filled with water, without the need to so large water injection rate in the unit interval, thus causes flow to decline, and then causes the wettability effect of coal body poor, cannot reach desirable dust-laying effect.As can be seen here, traditional static pressure water filling, because water fed distance is longer and the water injection pressure that causes of reason such as sealing difference is low, can not reach the effect required for on-the-spot depositing dust.
Summary of the invention
in order to overcome the growth of traditional static pressure water flooding regime along with water injection time, can produce that penetration reduces, degradation problem under flow, then the defect to coal body wettability effect difference is caused, the utility model provides a kind of coal-seam high-pressure pulsating water hammer water-infusion device, this water hammer water-infusion device can make injection flow invariable, thus more effectively, moistening coal body equably, to reach dust-laying effect better.
