针对目前撒布岩粉惰化技术、被动式阻隔爆技术、自动阻隔爆技术的局限性,提出构建固体阻隔爆装置应用在煤矿采掘工作面,设计并阐述了在圆拱形巷道、矩形巷道、梯形巷道中该装置的结构形式及动作原理,该固体自动阻隔爆装置,可以消除瓦斯煤尘爆炸时火焰锋面高温灼烧、冲击波超压破坏和井巷有毒有害气体的危害和影响,同时具备重复作用及使用性,能够对井下爆炸后的二次爆炸或多次爆炸发挥阻隔爆作用。
Aiming at the limitations of current inerting technology, passive barrier explosion technology and automatic barrier explosion technology, the authors put forward the application of building solid barrier explosion device in coal mining face, and design and elaborate the application of the technology in the arched roadway, rectangular roadway, trapezoidal roadway In the structure and action of the device structure, the solid automatic block explosion device, you can eliminate gas explosion in the combustion of the flame front of the high temperature fire damage, blast damage and overwhelming toxic and harmful gas wells harm and have the same time, Usability, can play a blocking explosion effect on the secondary explosion or multiple explosions after the underground explosion.
