摘 要: 提出了煤体注入阻化液防治煤炭自燃技术,通过高压将阻化液注入煤层,阻化液可均匀渗入煤体中的孔隙,因此开采后被丢入采空区的煤体不论如何破碎,均可被阻化液均匀包裹,隔绝了煤炭表面与氧气的接触,从而起到防止氧化、延长自燃发火期的作用。在新阳矿S1105工作面实行了长孔注入阻化液技术方案,实验证明此技术具有很好的防火效果。
关 键 词: 煤化学工程;煤炭自燃;高硫煤;Na2CO3阻化剂;阻化液

Abstract: The paper proposed a technology injecting inhibitor liquor into coal. The inhibitor liquor injected into coal with high pressure may permeate evenly into coal pores. No matter how cracked the coal is, it can be evenly surrounded by the inhibitor liquor. The inhibitor liquor isolates coal from air, thus it can prevent oxygenation and prolong time of spontaneous combustion, which provide assurance for safety mining. The technology was applied to S1105 work surface of Xinyang mine, and the experiment results showed that the technology had good fireproofing effect.
Key words: coal chemistry engineering; spontaneous combustion of coal; sulfur-coal; Na2CO3 inhibitor; inhibitor liquor
