頂(ding)板離層儀的安裝(zhuang) 

為了準確反映頂板(ban)變化情(qing)況，離(li)層儀要緊跟工(gong)作(zuo)面迎頭安(an)裝，在安(an)裝后(hou)工(gong)作(zuo)面10米(mi)內的離(li)層儀要每班進行觀測記(ji)錄(lu) 

安裝步驟

（1）用錨桿(gan)鉆(zhan)機∮26mm鉆(zhan)頭打7m—8m深的孔； 

（2）深(shen)部(bu)基點(dian)：用安(an)裝桿(gan)將深(shen)部(bu)基點(dian)錨固(gu)(gu)器(qi)推(tui)入孔(kong)中(zhong)，直至孔(kong)底，抽(chou)出安(an)裝桿(gan)后，手拉一(yi)下鋼絲(si)繩，確認錨固(gu)(gu)器(qi)已(yi)(yi)卡(ka)住(zhu)(zhu)，深(shen)部(bu)基應固(gu)(gu)定(ding)頂板(ban)以上7m—8m處(chu)； 淺(qian)部(bu)基點(dian)：用安(an)裝桿(gan)推(tui)入淺(qian)部(bu)基點(dian)錨固(gu)(gu)器(qi)至2.3米(mi)處(chu)，抽(chou)出安(an)裝桿(gan)后用手拉一(yi)下鋼絲(si)繩，確認錨固(gu)(gu)器(qi)已(yi)(yi)固(gu)(gu)定(ding)住(zhu)(zhu)； ;

（3）對準刻度：將(jiang)(jiang)粗(cu)讀數筒(tong)和(he)(he)孔(kong)口套管下(xia)邊(bian)緣對齊，將(jiang)(jiang)其(qi)繩(sheng)(sheng)(sheng)卡卡死(si)，頂(ding)板(ban)離層指示儀(yi)，并截(jie)去多余(yu)鋼(gang)繩(sheng)(sheng)(sheng)：將(jiang)(jiang)細(xi)讀數筒(tong)與粗(cu)讀數筒(tong)下(xia)邊(bian)緣對齊，將(jiang)(jiang)其(qi)繩(sheng)(sheng)(sheng)卡卡死(si)，并截(jie)去多余(yu)鋼(gang)繩(sheng)(sheng)(sheng)，為方(fang)便(bian)統一，數顯式頂(ding)板(ban)離層指示儀(yi)，細(xi)筒(tong)和(he)(he)粗(cu)筒(tong)的基讀數值都設(she)置(zhi)在10mm處。

①采用(yong)頂(ding)板(ban)(ban)(ban)(ban)離(li)層(ceng)指(zhi)示(shi)儀(yi)監測(ce)頂(ding)板(ban)(ban)(ban)(ban)離(li)層(ceng)。Ⅳ、Ⅴ類煤層(ceng)巷道均必須進行頂(ding)板(ban)(ban)(ban)(ban)離(li)層(ceng)監測(ce)，井下設(she)記錄牌板(ban)(ban)(ban)(ban)顯(xian)示(shi)。其(qi)(qi)他類別煤巷的(de)(de)頂(ding)板(ban)(ban)(ban)(ban)離(li)層(ceng)檢(jian)測(ce)由礦總工程師根(gen)據(ju)(ju)具體情況確定(ding)。②頂(ding)板(ban)(ban)(ban)(ban)離(li)層(ceng)指(zhi)示(shi)儀(yi)的(de)(de)安(an)(an)設(she)數量(liang)參照下表。③離(li)層(ceng)指(zhi)示(shi)儀(yi)的(de)(de)安(an)(an)設(she)要及時，其(qi)(qi)距離(li)迎(ying)頭不(bu)大于15米，安(an)(an)設(she)位置在巷寬(kuan)的(de)(de)中部。④頂(ding)板(ban)(ban)(ban)(ban)離(li)層(ceng)臨(lin)界值。離(li)層(ceng)臨(lin)界值因地質條(tiao)件、采動影響(xiang)等(deng)因素(su)不(bu)同而(er)異。各礦應根(gen)據(ju)(ju)本礦條(tiao)件，經過試驗研究，lby 2h頂(ding)板(ban)(ban)(ban)(ban)離(li)層(ceng)指(zhi)示(shi)儀(yi)，取得具體條(tiao)件下的(de)(de)離(li)層(ceng)臨(lin)界值。
