双鸭山东荣一矿 矿井通风设计

煤矿资料

摘 要

本设计依照高产高效的理念，根据该井田范围、地质构造、水文特征、煤层赋存条件及煤质等情况进行了井田通风设计，并将井田开拓方式确定为立井开拓，多水凭、集中大巷、分区石门布置。

每个矿井的通风状况都直接关系到矿井生产能否安全顺利进行，关系到矿山工人的安全和健康，而良好的通风状况又是以完善的通风系统为基础。对于该设计矿井，根据煤质特征、煤层赋存状况确定了矿井的中央并列式通风方式。采区风量依据“按须配风”的原则，确定工作面、掘进面风量，进而确定整个矿井的总风量。并且通过对风阻的调节使我们对矿井通风的前期和后期风阻的不同有了更好的、清晰的认知，在完成通风设计的同时我们又着眼于矿井的常见事故，并提出防治措施。

Abstract

High yield and efficiency in accordance with the design concept, according to the scope of the mine field, geological structure, hydrological characteristics of coal seam occurrence of such conditions and to develop a preliminary mine design, preliminary to determine the location of the shaft, to open up the way, roadway layout, mining zoning, layout mining area, tunnel selection and so on, for follow-up to prepare the design of mine ventilation.

Each of the ventilation shaft is directly related to mine safety production can proceed smoothly, related to mine safety and health of workers, and good ventilation and the ventilation system is based on a sound basis. Therefore, the design of mine ventilation is the key part of the design. The design for the mine, according to the characteristics of coal, coal bed situation to determine the occurrence of the central parallel mine ventilation. Mining area based on air volume, "to be allocated in

accordance with the wind" principle, determined face, driving the volume of surface wind, and the entire mine to determine the total air volume. Air volume will be allocated to different locations with the wind is the focus of the ventilation design. And the regulation of wind enabled us to mine ventilation pre-and post-Drag a better difference, a clear understanding of the design of the completion of ventilation at the same time we have a common focus on mine accidents, and prevention and control measures.

Keywords: Mine development Mine ventilation Ventilation structures To deal with disaster prevention
