摘　　要：为减小24110综采工作面初次来压时顶板大面积垮落而形成的飓风,避免造成工作面设备和施工人员受伤,采用深孔预裂爆破技术强制放顶,根据煤层顶板破拆原理,并结合4上号煤层顶板实际情况,58个炮眼分别设计在工采面两条顺槽内,以保证工采面初压时的安全生产。In order to reduce the hurricane caused by the large-scale collapse of the roof during the initial pressure of the 24110 fully mechanized mining face,which caused injuries to the equipment and construction personnel of the working face,deep hole pre-splitting blasting technology was used to force the roof caving.Based on the principle of coal seam roof demolition and according to the actual situation of the roof of the 4th upper coal seam,58 blast holes are designed in two grooves of the mining face respectively,so as to ensure the safe production during the initial pressure of the mining face.
