2月17日，神華神寧煤業集團棗泉礦通過“跳采”工藝重新安裝的110202綜放工作面順利通過驗收，正式投入回采。這也是該礦首次探索以“跳采”方式過斷層。
該工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)走向(xiang)長度2820.5米(mi)，傾斜長度267.4米(mi)，設計儲量(liang)610萬噸，在回(hui)采(cai)(cai)兩個(ge)月之后(hou)(hou)遇到走向(xiang)長度233米(mi)，落差9至15米(mi)的(de)DF42正(zheng)斷(duan)層(ceng)(ceng)(ceng)（含水巖層(ceng)(ceng)(ceng)）。在過斷(duan)層(ceng)(ceng)(ceng)方案(an)制訂過程中，該礦(kuang)綜合考(kao)慮回(hui)采(cai)(cai)成(cheng)本、煤(mei)炭質量(liang)及煤(mei)炭回(hui)收率(lv)等(deng)諸多因素，經對比(bi)論證(zheng)并報上級主管(guan)部門批準，決定采(cai)(cai)取“跳(tiao)采(cai)(cai)”方式在斷(duan)層(ceng)(ceng)(ceng)前方新(xin)開一(yi)個(ge)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)，將(jiang)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)設備(bei)轉(zhuan)場“挪”至新(xin)開切眼，從而將(jiang)斷(duan)層(ceng)(ceng)(ceng)“甩(shuai)”到工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)后(hou)(hou)方，“跳(tiao)”出斷(duan)層(ceng)(ceng)(ceng)阻攔。承擔(dan)該工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)回(hui)采(cai)(cai)的(de)綜采(cai)(cai)三隊，克服了工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)轉(zhuan)場過程中設備(bei)拆運(yun)安(an)裝(zhuang)一(yi)系列(lie)難題，嚴把安(an)全(quan)管(guan)理和安(an)裝(zhuang)質量(liang)關(guan)，加班加點，歷時35天完(wan)成(cheng)了“跳(tiao)采(cai)(cai)”任務，新(xin)安(an)裝(zhuang)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)一(yi)次試(shi)運(yun)轉(zhuan)成(cheng)功。比(bi)同等(deng)條件、同等(deng)回(hui)撤工(gong)(gong)(gong)藝(yi)的(de)工(gong)(gong)(gong)作(zuo)(zuo)(zuo)面(mian)提(ti)前了15天，既避免了回(hui)采(cai)(cai)過斷(duan)層(ceng)(ceng)(ceng)給全(quan)礦(kuang)煤(mei)質造成(cheng)的(de)嚴重影響(xiang)，還為(wei)全(quan)年(nian)安(an)全(quan)高效生產(chan)贏得了時間(jian)。
