Dustproof forestope

Abstract

The invention relates to a dustproof forestope with a good dust falling effect. The dustproof forestope comprises a forestope body, wherein two ends of the forestope body are connected with baffles in a sealed manner ; one of the baffles is provided with a through hole; a pipe wall of the forestope body is provided with a round hole; a spraying pipe is fixedly connected inside the forestope body; an atomizing water curtain sprayer is communicated on the spraying pipe in a sealed manner; the atomizing water curtain sprayer is corresponding to the round hole; one end of the spraying pipe is closed, and the other end of the spraying pipe is communicated with a high pressure pipe connector in a sealed manner; and the high pressure pipe connector passes through the through hole and extends to the outside of the baffle. According to the invention, the functions of a remote spraying device and a forestope are combined into one; when the dustproof forestope is used, the pressure water conveyed by an underground high pressure water pipe is taken as a water source and is conveyed to the head-on closure by a high pressure rubber pipe; and the purpose of dust falling is achieved by water curtains produced by the atomizing water curtain sprayer, so that not only the safety of head-on temporary support is guaranteed, but also the fully-closed dust falling process is realized, and good using effect is obtained.

Description

technical field [0001] The invention relates to a mining device, in particular to a dust-proof front probe beam. Background technique [0002] At present, in coal roadways and semi-coal and rock roadways constructed by the drilling and blasting method, blasting and pick-up are the most important dust-producing processes, and the head-on dust production accounts for 80% of the dust production in each process. Generally, spray curtains or spray rods are used as measures. However, due to the impact of blasting, it is difficult to fix the spray curtains and spray rods before rake installation, and the formed water curtain is difficult to cover the entire head, and the dust suppression effect is not good. Life poses a serious threat. Contents of the invention [0003] The purpose of the present invention is to provide a dust-proof front probe beam with good dust-reducing effect. [0004] To achieve the above object, the technical solution adopted in the present invention is: ...
