SU1461989A1 - Method of airing mine working in operation of self-propelled hauling vehicle - Google Patents

Abstract

The invention relates to mining. The goal is to increase the ventilation efficiency of the dead-end operation due to the intensification of fresh air supply to the driver's work zone. Fresh air is supplied through the injection pipeline as the loading and hauling machine moves from the mouth of the mine to the bottom plane. The suction pipe removes polluted air as the machine moves from the intake plane to the wellhead. At the time of loading the loading and hauling machine, fresh air is supplied and REMOVED simultaneously. During the period of the unloading of the car and its approach to the outfall, polluted exhaust gases are removed from it by ventilation flow. Further movement of the machine to the bottom is carried out towards the fresh air. 2 ill., 1 tab. § WITH

Description

one

The invention relates to mining and can be used for airing a dead-end mine during operation of a self-propelled loading and hauling machine (PDM) with an internal combustion engine (ICE).

The purpose of the invention is to increase the efficiency of airing a dead-end mine when operating self-propelled loading and hauling machines with an internal combustion engine in them due to the intensification of fresh air supply to the driver’s work area.

FIG. 1 shows a scheme for implementing the method of airing a dead-end mine during operation of a self-propelled loading and hauling machine; in fig. 2 - generation, transverse

cross section. I

The diagram shows a self-propelled loading and transporting machine with a diesel engine, drive 1, pressure 2 and suction 3 fans, and pressure 4 and suction 5 Tpy6fini (i-water, detonated mining mass 6.

When carrying out the method of ventilation of the dead-end mine, pressurized 4 and suction 5 metal pipelines, each not more than 10 m from the bottom, are laid along the walls of the mine. The performance of both the injection and the suction, for example, the fan was adjusted depending on the amount of air that had to be supplied to the bottom-hole production space.

When the machine 1 moves into the bottomhole space, the ventilation was carried out only due to the operation of the injection fan 2. The ventilation air moves towards Pda 1 and carries the exhaust gases of the internal combustion engine into the outgoing ventilation flow. During the loading time of the blasted rock mass 6, simultaneously with the injection fan 2, the aspirator 3 is also in operation.

This is accomplished by operating the blower 2 fan, and the suction 3 fan is turned off. Switching the fans on and off is performed by the PDM driver, for which electric starters are located at the mouth of the fabing and after the slaughter.

10 During the period of unloading the PAD and her. . an exhaust flow is completely removed from the entrance to the production mouth from it by two vents, and the further movement of the CMC in the bottom is carried out towards the fresh air. The change in the amount of poisoned gases in the ventilation air in the dead-end, workings during the operation of self-propelled machines with internal combustion engines in them is presented in the table.

When the PDM moves to discharge from the inlet to the outflow mouth, the pressure fan 2 is turned off, and the suction 3 is turned on. At the same time, fresh air flows towards the movement of the material and the gas is removed from the heat exchanger through the suction line. After leaving the PDM from the ventilated production, it is sent for unloading, and airing 35 in order to increase the ventilation efficiency of the dead-end operation due to the intensification of fresh air supply to the driver’s work area, fresh air is supplied as the loading and hauling machine moves from the mouth of the mine to the bottom of the slaughter air while the cargo is moving from the plane to the mouth of the bridge, while at the same time as the loads of the loading and hauling machine, fresh air is supplied and the polluted air is discharged simultaneously. five in order to increase the ventilation efficiency of the dead-end operation due to the intensification of the supply of fresh air to the driver’s work area, the supply of fresh air is carried out during the movement of the loading and hauling machine from the mouth of the mine to the bottom plane, and the removal of contaminated air machines from the plane to the mouth of the bridge, while at the time of loading the loading and hauling machine, the supply of fresh air and removal of polluted air are carried out simultaneously. i I S to about m; e and at) about X but V oh oh with " about about g U 1L about "S- tfl g g 1LU-I emsm Ooh oo oo Ik "i oo cho vO si " oh oh oh oh 9 91 am 1L "(M oh oh S 1G | WITH "M JV with oh oh VO in "About with oh i what is his name   eat about "- - I oh oh M M with vo oh oh 00 (M oh oh sm “With h ABOUT) about,  / XJ / vx f / 5 / vv fff l / vy / - f f wy / IT / f / Y   - A .V i vtti; “W / f // five W.
