一、前言煤炭自然发火是煤炭生产中的一大灾害。它不仅影响煤炭的正常生产,使国家煤炭资源遭受损失;而且严重的威胁职工人身安全。我局多年来对采区防火主要是用黄泥灌浆,效果较好。但是,随着燃炭工业的迅速发展,现有的防火技术已不能满足生产的需要。为此,需要我们试验阻化剂防火技术。 First, the preface Coal spontaneous combustion is a major disaster in coal production. It not only affects the normal production of coal, causing losses to the country’s coal resources; it also seriously threatens the personal safety of workers. For many years, our bureau has adopted the yellow mud grouting for the fire prevention in the mining area and the effect is better. However, with the rapid development of the carbon burning industry, the existing fire prevention technology can no longer meet the needs of production. To this end, we need to test the fire retardant retardant technology.
