The invention relates to the mining industry and can be used to suppress dust during loading and reloading of the conveyed bulk materials in underground workings and surface complexes.

Known construction and arrangement of paragraphs peace with the outlet and is connected through a valve to regulate the flow of fluid with a sensitive element, made in the form mounted on a horizontal shaft plate, one end of which is mounted for contact with bulk material, and the other via Cam is kinematically connected with the valve for regulating the fluid supply. The disadvantages of the known irrigation devices are not excluded breakdown of the irrigation device in the presence of the transported material "oversized"; when unexpected stops of the conveyor and in the presence of cargo being transported on the conveyor belt free after water from the nozzle onto the conveyor belt that leads to excess water, wetlands transshipment point of the transported material.

The closest to the technical nature of the present device is fully automatic irrigation site loading of bulk materials, comprising a pipe for supplying fluid communication with the fill associated with the last sensor element made in the form of two shoulders of the lever, one arm of which is installed with the possibility of contact with bulk material, and the other is connected with the shut-off valve [1] the mechanism of rotation of the sensing element and the shut-off valve, which feeds the secure adequate performance of the device at random stops of the conveyor with the transported cargo, do not provide reliable operation in thick waters.

The objective of the invention is to increase the reliability of the device by eliminating the clogging of the nozzle and potential damage from the "oversized" in the transported material, improve the performance of the device at random stops conveyors, and also simplify the design of the device.

This is achieved by the fact that in irrigation device loading and transshipment of items of mining enterprises, consisting of a pipe for supplying fluid communication with the fill associated with the last of the sensing element in the form of two shoulders of the lever, one arm of which is installed with the possibility of contact with bulk material, and the other is connected with the shut-off valve, two shoulders lever pivotally mounted on the suspended movable support in a vertical position, the upper arm of the lever is made in the form of twin forks in the opening where the shut-off valve, made in the form of a reflective liquid concave razdobreevoy plate, posted on shifted up vertically relative to the outlet of the fill horizontal axis perpendicular to the outlet of the fill with Uglova what about the vertically relative to the outlet of the fill at a distance of 0.5-1.0 hole diameter. In addition, the difference consists in that the end part of the fill is made of elastic material.

In Fig.1 schematically illustrates the device of Fig.2 is a view along arrow a in Fig. 1; Fig.3 section b-b of Fig.2; Fig.4 section C-C in Fig.3.

The irrigation device of cargo handling items mines consists of a frame 1, on which by means of the hinge 2 is suspended from a support 3. The sensing element in the form of two shoulders lever pivotally mounted on a moveable support 3, the lower larger shoulder 5 is placed with the possibility of contact with the transported falling material, and the upper shoulder 6 provided with a locking valve 7, which is made in the form of a reflective liquid concave razdobreevoy plate and placed on the offset vertically upward relative to the outlet 8 fill 9 the horizontal axis 10 with the possibility of angular displacement. The end part of the nozzle 9 provided with an elastic sealing material 11, while the upper lower shoulder 6 made in the form of twin forks 12, in the opening where the locking valve 7. The stop 13 is mounted on one of the terminals of the plug 12 to limit the turn-off valve 7. The material to be conveyed is overloaded redlagaemoe the device is as follows.

In the initial position in broken lines 14 and 15, when the traffic there is, the sensing element 4 under the action of gravity lower large shoulder 5 is placed vertically (or at an angle close to vertical). The initial position of the sensing element 4 depends on the length of the lower arm, the weight, and the water pressure in the fire the pipeline mine. In any case, the original position it is determined experimentally. Thus locking the valve 7 is placed perpendicular to the discharge opening 8 fill 9 and tightly pressed against the elastic sealing material 11, which eliminates the expiry of water from the nozzle 9. When enabled, drives the conveyors 14 and 15 are transported by falling material sensitive element 4 will be deflected from the vertical position, the upper shoulder 6 will be displaced by some angle and release the locking valve 7. Flowing under pressure jet of water will reject him at some angle that is limited by the stop 13. Deviation-off valve 7 is due to the fact that as mentioned above, the locking valve 7 is placed in the opening of the upper arm 6 of the sensing element 4 on the horizontal axis 10, which in turn shifted vyhodnogo holes 9. Flowing out of the fill water under pressure 0.6-0.8mpa in contact with the metal inclined located concave surface of the locking valve 7 is sprayed, forming a flame melkodispersionnoy water. In the absence of a feed conveyor 14 of the bulk material when operating the conveyors sensitive element 4 with the transported falling material is not sensitive element 4 will occupy a vertical initial position, the upper shoulder 6 will press the locking valve 7 to the outlet 8 of the nozzle 9 and the flow of water stopped, and after the water happens almost instantly, as the locking valve is placed directly at the outlet unlike the prototype, where between the valve and the nozzle there is a segment of the pipeline, ensuring the expiry of water for some time after shut-off valve. The overlap of the fill will happen at random stops the conveyors 14 and 15 (unanticipated withdrawals of voltage drives conveyors), because the deflecting flow of the transported material will not be that will reduce fluid flow. When the movement of the conveyors and the presence of large "oversized" damage irrigation devices are not pradlagaetsja in the direction of movement of the latter. After the passage of the "oversize" through transshipment point irrigation device will return to its original position, continuing to operate normally.

SUBSTANCE: invention is related to the field of mining, in particular, to safety issues in coal mines, namely to explosions of methane caused by friction spark created as a result of mine machines picks friction against hard rocks. Method is suggested to assess danger of rocks regarding friction inflammation of air-methane mixture, which consists in the fact that rock samples are taken, their strength and content of silicon dioxide are determined, and then tests are carried out at test bench danger of friction sparking. In order to perform test, explosive mixture is formed in test bench, and nominal cutting speed is increased 1.5 times. If at hardness of rocks f from 3 and content of silicon dioxide up to 30% no inflammations were observed and no friction sparks were produced, then rock is considered safe. If at hardness of rock from 3 to 5 and silicon dioxide content from 30 to 50% with availability of friction sparks with temperature of up to 300C and absence of inflammations, rock is considered as spark-hazardous of the 1st extent, and if their temperature is more than 300C - to spark-hazardous of the 2nd extent. If at least one inflammation occurred from friction sparks, rock is considered highly explosive. Use of suggested method makes it possible to increase safety of cleaning and preparatory works.
