深孔预裂爆破工程可减少老顶初次来压步距过大造成的灾害，在15号煤层中显得尤为重要。论文针对三元晋永泰煤矿顶板特性，改进综采强制放顶方案，采用深孔预裂爆破，提高了爆破效果，大幅地降低了初次来压的强度和初次来压形成飓风的可能性，达到综采面安全回采的目的。
深孔預裂爆破工程可減少老頂初次來壓步距過大造成的災害，在15號煤層中顯得尤為重要。論文針對三元晉永泰煤礦頂闆特性，改進綜採彊製放頂方案，採用深孔預裂爆破，提高瞭爆破效果，大幅地降低瞭初次來壓的彊度和初次來壓形成颶風的可能性，達到綜採麵安全迴採的目的。

using the deep hole pre split blasting can reduce the disasters caused by the too large roof ifrst weighting interval, it is particularly important in the No. iffteen coal seam. According to the roof characteristics of sanyuan jin Yongtai coal mine, reformed the forced caving scheme in fully mechanized caving face, using the deep hole pre-splitting blasting, to improve blasting effect, greatly reduced the possibility of initial pressure and initial pressure of the strength of a hurricane, and achieved the purpose of safety mining in fully mechanized coal mining face.
