Abstract
The invention provides a dust control device and a dust control method of a fully-mechanized excavation workface, belongs to the technical field of dust prevention of an operation room of a tunneling machine of a coal mine tunneling workface and aims at reducing dust concentration of the tunneling workface. The dust control device of the tunneling driving face comprises a dust control curtain rolling shaft and a curtain body. The dust control method of the tunneling driving face is characterized in that an air cylinder is distributed in a roadway on one side of the driver operation room of the tunneling machine, and an air outlet of the air cylinder is located at the back of the driver operation room. Before the roadway is tunneled, a dust control curtain is longitudinally installed on a top plate anchoring net along the roadway, the curtain body is pulled out, and the roadway in a scope of the machine body length of the tunneling machine is longitudinally separated into two portions. The dust control device and the dust control method effectively reduce coal dust concentration of the driver operation room and the machine body of the tunneling machine.
Description
Technical field
The invention belongs to driving face in coal mine development machine operating room dust control technology field, be specifically related to fully mechanized workface control dust collecting method and device thereof.
Background technology
Because Mine Dust causes it when having explosion hazard because of himself physicochemical property, also have the precision equipment of reduction application life, reduce on-the-spot visibility, easily spontaneous combustion and cause connecing for a long time the dirt personnel and suffer from occupational disease.Consult related data as can be known, the development machine driver locates dust concentration up to 100 ~ 1000mg/m
3, respirable dust concentration is then up to 10 ~ 100mg/m
3, seriously surpassed allowable concentration.Therefore; no matter consider from ensureing the enterprise safety operation angle; or consider from protection operating personnel occupational safety and health angle; research driving face Dust Control Technology; reduce the dust concentration of driving face, for preventing the coal dust accident, improve operating environment, improving service life of equipment and prevention occupational disease etc. and have important practical significance.
Summary of the invention
The objective of the invention is in view of driving face distribution of air flow feature, design a kind of dirt curtain device of controlling driving face is divided into air intake and two relatively independent passages of return air, controlled vortex flow district dust spreads to driver position, fluerics.Enter the Dust Concentration of operating room by adjusting air duct mouth position and the effective control of control dirt curtain hanging position.
The present invention solves the problems of the technologies described above the technical scheme of taking to be:
The fully mechanized workface dust control device comprises control dirt curtain reel and curtain body, it is characterized in that: described control dirt curtain reel axis runout laneway midline is near development machine driver operation chamber one side; Two parts before and after control dirt curtain reel is divided into, anterior control dirt curtain reel is installed in the place ahead, development machine driver operation chamber, and anterior curtain body is transparent soft material; Rear portion control dirt curtain reel is installed in the rear of development machine driver operation chamber, and rear portion curtain body is soft material.
Fully mechanized workface control dust collecting method is characterized in that: air duct is arranged in the tunnel of development machine driver operation chamber one side, the air duct air outlet is positioned at rear, development machine driver operation chamber; Before the tunnelling, vertically to be installed in the top board anchor online along the tunnel will to control the dirt curtain, and the curtain body is pulled out, and the tunnel in the machine body of boring machine length range longitudinally is separated into two parts;
Described air duct air outlet apart from the distance of working face wall less than or equal to 10 meters.
The present invention compared with prior art has following beneficial effect:
Because adopting control dirt curtain device that the tunnel longitudinally is divided into two parts, the present invention make the driver be in the jet expansion segment; Because the effect of negative pressure field, control dirt curtain the inside, the fresh air of outside is through flowing inwards from here, and coal dust can from here to external diffusion, effectively not reduce the Dust Capacity at place, development machine driver operation chamber.
