The designed mine adopts method of opening of double upright well,and devides two recovery level . The mine adopts join layout to central exploit, and the big tunnel use 10 ton electrical engineering car to lead a bottom unload type mineral car transports, and the method of opening is strike longwall working ,and the coal cutting technology is prehensive mechanical exploitation,and the disposal methods of the goaf is all falls method. The main mine uses many rope rub box to promote, and the vice mine use the rigid bination cage to promote . The ventilating method of the mine is the central being juxtaposed the draw out type. key words method of opening join layout trike longwall all falls I 緒 論 大學四年的系統(tǒng)學習和實踐即將結束，在這四年里我掌握了很多專業(yè)知識，為了能更好的鞏固和運用這些知識，本次畢業(yè)設計我選做了黑龍江省雞西礦業(yè)集團城子河煤礦的新井設計。為了使本次設計更加準確合理，文中內容采用了 大量的計算 ,進行了方案比較。 開采順序 ............................
