落底(di)及(ji)硬化施(shi)(shi)工(gong)辦法(fa)： 落底(di)選用(yong)(yong)手鎬、風(feng)鎬及(ji)鐵鍬等(deng)工(gong)具進行(xing)；底(di)板為煤時，選用(yong)(yong)手鎬施(shi)(shi)工(gong)，底(di)板為巖 石(shi)時，選用(yong)(yong)風(feng)鎬施(shi)(shi)工(gong)。

落底(di)施(shi)工(gong)可分組進行，但(dan)各組間的(de)間隔不(bu)(bu)得小于(yu)5米(mi)。落底(di)有(you)必(bi)(bi)要嚴厲按腰線進行施(shi)工(gong)，落底(di)后巷道底(di)板到腰線不(bu)(bu)低于(yu)1.22米(mi)。落底(di)必(bi)(bi)后確(que)保(bao)巷道底(di)板平整。 施(shi)工(gong)時，停放礦車的(de)地(di)址，其負(fu)坡方向有(you)必(bi)(bi)要設置一道臨時十(shi)字(zi)(zi)阻(zu)車器（用(yong)兩根(gen)半圓木(mu)或軌枕在軌道上(shang)搭(da)成十(shi)字(zi)(zi)），且礦車車輪下選用(yong)木(mu)楔(xie)子(zi)穩定(ding)住，避免因落底(di)后軌道下落形成意外運輸事端(duan)。

落(luo)底的矸石(shi)（煤）選用(yong)人(ren)工裝入(ru)礦(kuang)車(che)(che)(che)人(ren)力(li)推(tui)(tui)車(che)(che)(che)外(wai)(wai)運至(zhi)北翼軌道大街(jie)。 人(ren)力(li)推(tui)(tui)車(che)(che)(che)每次(ci)只能推(tui)(tui)一(yi)個礦(kuang)車(che)(che)(che)，禁止在(zai)礦(kuang)車(che)(che)(che)兩側推(tui)(tui)車(che)(che)(che)。推(tui)(tui)車(che)(che)(che)時(shi)有(you)必(bi)要時(shi)刻注意前(qian)方。在(zai)開始推(tui)(tui)車(che)(che)(che)、停車(che)(che)(che)、掉道、發(fa)現(xian)前(qian)方有(you)人(ren)或有(you)障(zhang)礙物，推(tui)(tui)車(che)(che)(che)人(ren)有(you)必(bi)要及時(shi)發(fa)出警(jing)號(hao)。落(luo)底完結之(zhi)后(hou)除(chu)卸壓槽外(wai)(wai)巷道底板用(yong)混泥土硬(ying)化(hua)，硬(ying)化(hua)厚度為100mm。
