Abstract
The utility model relates to a ventilation arrangement system used for coal mining, in particular to a coal mine ventilation system which is suitable for a high gassy mine and solves a plurality of problems existing in a ventilation system in a coal extraction process on the conventional coal mine working surface. Five working surface roadways are adopted, three roadways are used for introducing air and two roadways are used for returning air and ventilating, so that a 'U+H-shaped' ventilation system is formed. The coal mine ventilation system has small ventilation resistance, large air flow cross section, large air volume and large gas discharge capability by air, and is suitable for mining in the high gassy mines.
Description
Technical field
The utility model relates to the ventilation arrangement system that uses in a kind of coal mining, is specially a kind of coalmine ventilation system that is applicable to high gassy.
Background technology
The ventilation system of stope working surface of coal mines is divided into into advancing for one time, one to advance for two times, two to be advanced two times, 3 one time, two and advances several ventilation system type two times, be suitable for the air-conditioning requirement of situations such as different mining conditions, roadway arrangement, coal-mining method, face take-over, the ventilation system that design alternative is different, for high Gassy Coal Face, above method has many problems not solve: as effective improvement of upper corner gas, the foundation of goaf gas drainage system, relationn of excavation and recovering anxiety, various disadvantages such as ventilation volume deficiency.
Summary of the invention
The utility model provides a kind of coalmine ventilation system in order to solve the problems that ventilation system exists in the existing coal mine work area exploitation process.
The utility model is realized by following technical scheme, a kind of coalmine ventilation system, roadway workface adopts five lanes to arrange, article three, two return air draft types of air intake, specifically comprise the two lanes that are arranged on work plane one side, wherein close on one of work plane and be the belt transportation of bearing work plane fortune coal, the air intake task air intake lane of holding concurrently, another is for bearing the air intake and the assistant conveyance lane of work plane material, equipment, personnel's transportation and work plane air intake; Also comprise three lanes that are arranged at the work plane opposite side, from inside to outside be followed successively by the assistant conveyance of bearing work plane air intake and the assistant conveyance air intake lane of holding concurrently, bear two return airways of work plane return air task; Wherein air intake and assistant conveyance lane end in the work plane place, and by connection roadway and belt transportation double air intake lane connection, belt transportation hold concurrently air intake lane, assistant conveyance hold concurrently before air intake lane and the work plane the passage perforation and be communicated with whole goaf, the assistant conveyance air intake lane of holding concurrently is communicated with second return airway by connection roadway respectively before and after the work plane, article two, return airway extends to inner end, goaf, and be communicated with herein, so form " U+H " type ventilation system.
Employing is advanced " U+H " type ventilation system of twice based on three, scraps three lanes behind the working face extraction, stays two lanes multiplexing as the tunnel of next work plane, and the roadway engineering of each work plane only need be dug three tunnels like this.
Compared with prior art, the characteristics and the advantage of " U+H " described in the utility model type ventilation system:
(1), each work plane has five tunnels, the tunnel arranges that in the work plane both sides flowing resistance is little, it is big to cross the wind section, air quantity is big, wind gas-removing ability is big, the exploitation of suitable highly gassy mine.
(2), the exploiting field inner working face adopts order mining, tunnel reusability height, work plane engineering quantity are little, help taking over of work plane.
(3), there is the ventilation negative pressure at the face upper corner angle rear portion, upper corner gas is difficult for transfiniting, and simultaneously, has also suppressed goaf gas and has gushed out to work plane.
(4), return airway is two lanes, changed the flow direction of upper corner place goaf gas, the multiplexing tunnel at work plane rear portion keeps its ventilation system, is convenient to personnel and enters the tunnel situation of observing, be convenient to roadway maintenance, saved the hidden danger that multiplexing gas-removing brings simultaneously.
Three advance " U+H " type ventilation system of two times.There is the ventilation negative pressure at the face upper corner angle rear portion, and upper corner gas is difficult for transfiniting, and simultaneously, has also suppressed goaf gas and has gushed out to work plane.Two return airways are arranged.All the time keep its ventilation system, blow-by, gas-removing not can timely and effectively be safeguarded, for next work plane has shortened the time of taking over.
(5), work plane side tunnel is the air intake lane, five lanes are arranged, are the air intake lane by the work plane both sides.Electromechanical equipment is arranged in the air intake lane, unstable airflow, and operating environment is good.
(6), the work plane both sides have an assistant conveyance lane respectively, the assistant conveyance lane is all arranged in the work plane both sides, be convenient to the maintenance of work plane crossheading belt, load center equipment, work plane material and personnel transport all in the air intake lane, transportation environment is good, and transportation is quick, and energy is timely, the safety processing device fault, the employee is short non-cutting time on and off duty, has alleviated personnel labor.
