Abstract
The invention relates to designing, manufacturing and construction technologies of danger avoiding, escaping and saving channels matched with coal mine underground working surfaces and laneway systems, in particular to a coal mine underground safety channel which comprises a pipeline, wherein the pipeline is paved from a mine mouth to a working surface along each branch laneway; the pipeline is formed by connecting a plurality of pipeline segments end to end; each pipeline segment comprises a spiral framework; foamed modified phenolic aldehyde layers are compounded on the inner wall and the outer wall of the spiral framework; and the spiral framework is prepared from non-foamed modified phenolic aldehyde and inflammable high-modulus fiber. The surfaces of the foamed modified phenolic aldehyde layers are carbonized in the presence of naked fire, and internal substances is isolated fully from the oxygen by using carbonized layers, so that the functions of insulating heat and preventing fire are realized, and thermal sources and dust can be effectively isolated during explosion and fire disasters; and after the non-foamed modified phenolic aldehyde and the inflammable high-modulus fiber are combined, the hardness and strength are enhanced greatly, and the tensile strength is 2-3 times that of a steel material, so that collapsed objects can be supported for keeping the channel unblocked during collapse of laneways.
Description
Technical field
The present invention relates to hedging, escape, the construction of rescue channels designs and use manufacturing and construction technology that a kind of colliery mining face under mine and roadway system cooperate, relate in particular to a kind of coal mine downhole safe passageway.
Background technology
Mine Dust, gas explosion accident happen occasionally, and usually cause huge personnel and property loss, cause great threat for underground work workman life security.In when, in the ore deposit gas explosion occuring when, at first, (1～2.5m/s) to detonation formula spread speed (2500m/s) from normal burning velocity for moving chemical reaction zone and high-temperature gas in the tunnel, the flame surface temperature can be up to 2150～2650 ℃, the flame face is through part, the people is scorched to death or large-area burns, and combustible is lighted and breaking out of fire.Secondly, damage envelope pressure is pressed onto 20 atmospheric pressure by several atmosphere, and the stack of forward direction shock wave and reflex time can reach 100 atmospheric pressure, and spread speed is fast, and the place of arrival causes casualties, and equipment and ventilation equipment damage, and collapses in the tunnel; Simultaneously, generate a large amount of pernicious gases after the gas explosion, if there is coal dust to participate in blast, the growing amount of CO is larger, often becomes the main cause of a large amount of injures and deaths of personnel.
At present, the down-hole is not effectively, practical special-purpose hedging escape safe passage, the inventor learns through retrieval, the patent No. is 200520052617.4 to disclose a kind of safety self-saving pipe of pit, the patent No. is 200410045499.4 to disclose a kind of mine automatic rescue pipeline, in above disclosed technical scheme, basically all comprise a body of laying along mine passage, and on the tube wall of this body, be provided with oxygen hose, the supporting facility such as Anti-slipping ladder and some illuminating lamps, the material of body is metal, plastics or other composite material, body is not prevented fires, compressive strength is inadequate, in case dangerous situation occurs, underground operators rarely can utilize the chance of these facilities, does not in fact also almost occur from the case of these facility approach escapes.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of energy fire prevention, resistance to compression, the coal mine downhole safe passageway of dangerous situation underground operators energy safety exit occurs.
In order to address the above problem, the present invention is achieved by the following technical solutions:
Coal mine downhole safe passageway of the present invention, comprise pipeline, pipeline is laid to work plane along each branch heading from well head, described pipeline is to be socketed to form from beginning to end by several duct sections, every duct section all comprises a spiral skeleton, all is compounded with foaming modification phenolic aldehyde layer on the inner and outer wall of described spiral skeleton.
Further, described spiral skeleton is to be mixed by the not foaming modification phenolic aldehyde of (percentage by weight) 50%-80% and the high modulus fibre that do not fire of (percentage by weight) 20%-50%.
Further, the internal diameter of described duct section is 1-2m.
Further, the thickness of described spiral inboard wall of skeleton is 1-3cm.
Further, the thickness of described spiral skeleton outer wall is 1-5cm.
Further, the end face diameter of described spiral skeleton or thickness are 1-5cm.
Further, an end of single duct section is provided with the protruding end, and the other end is provided with female end, connects together by cooperatively interacting of protruding end and female end between two adjacent duct sections.
Compared with prior art, the invention has the beneficial effects as follows: all be compounded with foaming modification phenolic aldehyde layer on the inner and outer wall of spiral skeleton of the present invention, foaming modification phenolic aldehyde layer is when meeting naked light, carbonization can occur in its surface, carburization zone is fully isolated with material and the oxygen of inside, have heat insulation and the fireproof function, blast and fire be effectively to isolate thermal source and dust, the spiral skeleton be by foaming modification phenolic aldehyde not and not so high modulus fibre make, not the foaming modification phenolic aldehyde and not so high modulus fibre in conjunction with after, its hardness and intensity strengthen greatly, tensile strength is 2-3 times of steel material, can support the thing that collapses when collapsing in the generation tunnel and guarantee that passage is unimpeded.
