選(xuan)礦(kuang)廠生產的(de)(de)尾(wei)(wei)礦(kuang)，主要用(yong)來做井下充填(tian)用(yong)。這(zhe)樣既解決了井下充填(tian)的(de)(de)材(cai)料問題，又(you)減少(shao)了環境(jing)污染，同時還提(ti)高了尾(wei)(wei)礦(kuang)庫(ku)的(de)(de)服務年限。選(xuan)別的(de)(de)終尾(wei)(wei)礦(kuang)由(you)泵打入充填(tian)濃縮(suo)機進行濃縮(suo)，溢(yi)流(liu)水(shui)返回(hui)水(shui)池作(zuo)(zuo)回(hui)水(shui)利用(yong)。經濃縮(suo)后的(de)(de)尾(wei)(wei)礦(kuang)由(you)泵送至尾(wei)(wei)砂(sha)充填(tian)系(xi)統進行分(fen)(fen)(fen)級，分(fen)(fen)(fen)級后的(de)(de)粗砂(sha)作(zuo)(zuo)為礦(kuang)場充填(tian)材(cai)料；只有少(shao)量的(de)(de)分(fen)(fen)(fen)級溢(yi)流(liu)（細(xi)顆粒）打入尾(wei)(wei)礦(kuang)庫(ku)。而干選(xuan)的(de)(de)尾(wei)(wei)礦(kuang)用(yong)來筑尾(wei)(wei)礦(kuang)壩(ba)。

矸石充(chong)(chong)填料需要(yao)將煤矸石破碎(sui)至5mm以下粒徑，并需保證(zheng)均(jun)衡的(de)含水率，所以充(chong)(chong)填系統(tong)要(yao)有破碎(sui)模塊和相應的(de)破碎(sui)前(qian)與破碎(sui)后室內堆(dui)場。純粉(fen)煤灰充(chong)(chong)填因(yin)粉(fen)煤灰懸浮性好攪(jiao)(jiao)拌比較(jiao)容易，高濃(nong)度的(de)矸石充(chong)(chong)填可(ke)以采(cai)用類似混(hun)凝(ning)土攪(jiao)(jiao)拌的(de)臥式攪(jiao)(jiao)拌槽，濃(nong)度較(jiao)低的(de)混(hun)合充(chong)(chong)填一般(ban)采(cai)用立式攪(jiao)(jiao)拌桶。充(chong)(chong)填系統(tong)的(de)組(zu)成單元(yuan)和功(gong)能(neng)不同(tong)。

充填(tian)工(gong)藝和(he)方式的因素(su)有哪些(xie)呢？    

   1.為了通過對(dui)充填(tian)(tian)體(ti)物理力(li)學性(xing)質和(he)對(dui)充填(tian)(tian)材料(liao)的認識，開發來源(yuan)更加廣泛(fan)、成(cheng)本更加低(di)廉，便于制(zhi)漿和(he)輸送，充填(tian)(tian)體(ti)強度(du)更高(gao)。       2.通過對(dui)探討，結合作業要求以及現代(dai)礦(kuang)山充填(tian)(tian)技(ji)術發展的趨勢，全尾(wei)砂膏體(ti)泵送充填(tian)(tian)系統，逐漸形成(cheng)了似膏體(ti)充填(tian)(tian)新思想。     

  充(chong)填領域前沿的(de)(de)技(ji)術是全(quan)尾(wei)砂(sha)膏體充(chong)填，全(quan)尾(wei)砂(sha)膏體充(chong)填的(de)(de)充(chong)填強度高、充(chong)填量大、機(ji)械化程度也高。這項技(ji)術的(de)(de)發展，給現有法提供了新的(de)(de)技(ji)術手段，變(bian)革(ge)了原有的(de)(de)分層(ceng)充(chong)填法為深(shen)孔大量法，、安全(quan)、綠(lv)色、環保。

注漿施工工藝及其有關參數注漿施工工藝主要有注漿設備的選擇、制漿工藝、灌漿工藝及注漿壓力的控制。2.4.1注漿設備注漿設備主要由制漿設備和注漿泵組成，如前注漿配置系統所述，制漿設備由一次攪拌池和二次攪拌池構成，目前采用的是施工單位因地制宜自制的攪拌設備，其容量和數量應工程大小而定。注漿設備常選用250型以上泥漿泵，這種泥漿泵市場較為常見，而且結實耐用。
