Abstract

This design in Dalong mine east three mining survey and geological characteristics of the basic conditions of mining area calculation of reserves, production capacity and service life of coal mining method of comparison and selection, coal mining process, mining production calculation within the mining area partitioning (divided into sections or stripe); This working face length, coal pillar size and meter; Mining roadway layout design including the location of the mining area up the hill to decorate and horizon, the mountain and segment (stripe) drift connection; Roadway cross section, supporting method selection, select the reasonable mining methods and mining method. Mining production system design; Stop process design working circulation homework; Cycle operation organization chart and personnel work. Secondly, according to the actual condition of the mining area east three mining ventilation system and ventilation method, according to the various locations required airflow, the wind of air flow distribution and calculation, determine the ventilation resistance. Methods include: mining ventilation system (should have corresponding ventilation structures), using wind place air volume calculation and distribution (by outside introversion, calculate a checking method of four). Total resistance ventilation resistance calculation: mining area, the structure size design and each branch of wind pressure balance calculation, determine the structure of pressure difference on both ends). This design adopts the mountain single wing mining of mining way, to the long arm coal mining method, using the comprehensive mechanized coal mining technology, with the mined-out area, a monk or nun beat all the data for mining ventilation system has carried on the preliminary design, the ventilation system of mining area, mining face ventilation system, the nuggets face ventilation has carried on the detailed calculation, the mining area, with emphasis on the air flow and ventilation resistance required.

Key words: Ventilation system; Ventilation resistance mining; Required air volume
