Abstract

The invention relates to a ventilation arrangement system in coal mining, in particular to a U+H type ventilation system which is suitable for a highly gassy mine and solves a plurality of problems of the conventional ventilation system in the coal mine working face mining process. Five tunnels are arranged to form a working face tunnel, wherein three air inlet tunnels and two air return tunnels forms an U+H ventilation system. The invention has small ventilation resistance and large wind-crossing section, air volume and windblown mine gas capacity and is suitable for the mining of the highly gassy mine.

Description

technical field [0001] The invention relates to a ventilation arrangement system used in coal mining, in particular to a U+H type ventilation system suitable for high-gas mines. Background technique [0002] The ventilation system of the coal mine mining face is divided into several types of ventilation systems: one inlet and one circuit, one inlet and two circuits, two inlets and one circuit, two inlets and two circuits, and three inlets and two circuits, which are suitable for different mining conditions, roadway layout, coal mining methods, ventilation requirements of working face replacement, etc., design and selection of different ventilation systems, for high gas working faces, many problems have not been solved by the above methods: such as the effective control of gas in the upper corner, the establishment of gas drainage system in gobs, There are many disadvantages such as tense mining relationship and insufficient ventilation. Contents of the invention [0003]...
