厚煤层综放面坚硬顶煤深孔爆破控制技术应用
|
摘要
为了提高顶板的爆破效果,实现工作面的安全高效生产,以潞新煤矿E4104综采面为研究背景,采用深孔爆破强制放顶技术,根据煤层赋存和施工技术条件,确定合理的钻孔布置、装药方式等关键技术参数,大大提高了顶板的爆破强度,现场试验效果显著,保证了工作面的安全高效生产,取得了良好的经济效益和社会效益。
In order to improve the blasting effect of roof and realize safe and efficient production of working face,deep-hole blasting forced roof caving technology was adopted in E4104 fully mechanized mining face of Luxin Coal Mine. According to the conditions of coal seam occurrence and construction technology, reasonable key technical parameters such as drilling arrangement,charging method and drainage were determined,which greatly improved the blasting intensity of roof,recieved remarkable effect of field test and guaranteed the safe and efficient production of working face.
