| 摘 要： | 针对急斜水平分段放顶煤中顶煤注水弱化问题,采用现场注水弱化工业试验对乌鲁木齐矿区B1+2煤层进行注水弱化研究,对顶煤弱化必要性进行了论证,提出了注水弱化工艺参数,运用光学钻孔窥视仪对注水煤体破坏程度和范围进行了检测,从注水前后效果对比可以得出预注水软化顶煤技术是急斜煤层安全高效开采的有效途径.

| Abstract: | According to the problem of cracked top coal for horizontal section top coal in steep seam using water injection technology and by the use of on-site water injection test,the water injection of B1+2 seam of Urumqi coalfield are reasearched,the necessity of top-coal weakening is proved,and water weakening process parameters was proposed.With the help of optical peep,the damage and scope of injection coal was detected.Water injection technology of steep thick seam in top-coal is a safe and efficient method th... |
