Abstract

The invention discloses a mine roadway fixed-point hydrogen sulfide collection device and method. The device comprises a remote controller and a trailer. A motor and a bearing alloy plate are arrangedon the trailer; an alloy steel round rod is arranged between the bearing alloy plate and the front end of a thickened alloy plate; an arc steel plate is arranged between the bearing alloy plate and the rear end of the thickened alloy plate; the arc steel plate is provided with an operation table with an operation button; a ranging module is arranged at the front end of the thickened alloy plate;a sliding conical cylinder sleeves the alloy steel round rod; and the front end of the sliding conical cylinder is connected with a plurality of collection cavities for collecting roadway hydrogen sulfide at fixed points. The remote controller controls the roadway fixed-point hydrogen sulfide collecting device to move forwards and stop when reaching the set head-on distance of the front roadway, controls a sliding conical cylinder to move forwards until the 2 # and 3 # concentric reducer pipes are away from intersection points A and B of the middle line and the left and right sides of the roadway and the 1 # concentric reducer pipe is away from the height H right above the middle point c of the roadway bottom plate, and a gas sample is collected in real time. The device is simple in structure, automatic in control and safe in gas production.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a fixed-point hydrogen sulfide collection device and method for a mine roadway suitable for driving and mining a coal seam rich in hydrogen sulfide gas. Background technique [0002] At present, coal seams rich in hydrogen sulfide gas are harmful to the health of coal miners during excavation and mining. Low concentrations of hydrogen sulfide can affect the eyes, respiratory system and central nervous system, while high concentrations of hydrogen sulfide can be fatal in a short time. . [0003] In coal mining, the abnormal gushing and disaster accidents caused by the abnormal enrichment of hydrogen sulfide gas in the coal seam are constantly appearing at home and abroad. H 2 The sudden gushing of S gas caused an accident. Since the density of hydrogen sulfide gas is 1.537kg / m 3 , heavier than air, often "suspended" in the middle and lower areas of the roadway. In or...
