摘　　要：井巷掘进爆破工程中，工作面按设计要求，布置各种斜形炮孔，利用量角器和垂直尺控制钎杆与工作面夹角，使炮孔钻孔精度与设计炮孔角度基本上符合，在生产中取得了良好的爆破效果．In the blasting of roadway drivage, the work-face Should be designed to meet the requirements and various inclined holes should be properly arranged. The angle included between the shaft her and the work-face can be controlled by means of a angle protractor and a ruler. The drilling precision should be basically conformed with the angle of the hole designed and good blasting effect can thus be obtained in the production process.
