调节风压防灭火方法(通常称为均压通风),目前已为不少矿采用.它具有方法简单,容易掌握的特点,其所需设备和材料也不难解决.调节风压是基于提高通风技术管理,防止漏风而做好防灭火工作,现已成为矿井防灭火必要的综合措施之一.一 调节风压的基本原理对空气施加一定的压力,使其流动,这个压力叫做风压.在矿井内,风压差(△P)与风量(Q),风阻(R)有如下关系式:
Adjusting the air pressure fire extinguishing method (usually referred to as pressure equalizing ventilation), has been used for many mines.It has a simple method, easy to grasp the characteristics of the required equipment and materials is not difficult to solve.Adjustment of wind pressure is based on increased Ventilation technology management, to prevent air leakage and do a good job in fire prevention and extinguishing work, has now become a mine fire prevention necessary integrated measures.A basic principle of regulation of wind pressure on the air to exert a certain pressure to flow, the pressure is called wind pressure. In the mine, the pressure difference (△ P) and air volume (Q), wind resistance (R) has the following relationship:
