摘　　要：采用相似原理,建立数学模型,并采用matlab编程,实现输入巷道的基本参数以及钻机参数,即可设计出巷道在终孔面以及终孔面与采掘面之间所需布置钻孔的孔长、方位角、倾角及终孔坐标参数,最终实现掘进巷道整体分布和每个断面钻孔布置的三维立体化显示。针对具有突出危险性梯形掘进巷道工作面前方煤体进行钻孔设计,实现一次性批量布孔。Similar principles were used to establish the mathematical model. By programming with matlab, it realized inputting basic parameters and rig parameters of the roadway, and got the hole length, azimuth, dip angle and final hole coordinates of final hole surface and between final hole surface and mining face. Ultimately it achieved three - dimensional display of the overall distribution of driving roadway and the layout of each cross - section drilling. Aiming at coal samples ahead of the working face of the trapezoidal driving roadway with outburst risks, it made drilling design and finished batch hole arrangements at one time.
