<p>　　曾經(jīng)成功爆破“天下第一爆”的惠州港移山填海爆破工程、“中國第一爆”廣州體育館整體爆破拆除工程、“亞洲第一爆”的寧波鎮(zhèn)海150米高煙囪雙向折疊爆破工程的廣東宏大爆破工程有限公司為什么這次會“失手”?事故原因初步查明為小爆破引發(fā)地下殘留的炸藥同時爆炸,最終釀成慘劇。</p> <p>　　<strong>爆破方案未考慮地下情況</strong> </p> <p>　　39歲的湖南人姜志武,是廣東宏大公司雇用的合同爆破工。事發(fā)當(dāng)時,他和工友姚天友在大峰礦羊齒采區(qū)技改露天剝離工程2140作業(yè)平臺實(shí)施解炮作業(yè)。而事發(fā)地點(diǎn)就在他們頭上不遠(yuǎn)處的2149作業(yè)平臺。</p> <p>　　斷斷續(xù)續(xù)干了爆破20多年,姜志武還是第一次遇到危險(xiǎn)。“按照正常程序是很安全的”,姜志武越想越后怕。像往常一樣,姜志武和工友躲在警戒線內(nèi)正方形的鋼板房內(nèi),等待爆破成功。2140作業(yè)平臺的爆破聲剛一停,隨后一聲“驚天地、泣鬼神”的怒吼,“像地震一樣”,大山開始晃動,姜志武的頭碰到鐵板房的鐵壁,一陣炫暈,隨后不省人事。</p> <p>　　那一刻,在2149作業(yè)平臺負(fù)責(zé)起炮的爆破員謝志才和胡振強(qiáng)等4位爆破人員所在的鋼板房炸開了花,事后搜救人員使用電焊工具才得以將擰成麻花的鐵板房分離開。</p> <p>　　“無非是藥量大了”,但讓姜志武感到不解的是,他們執(zhí)行的只是再普通不過的常規(guī)爆破任務(wù),即使是使用硐室爆破法的2149作業(yè)平臺,往常也不會產(chǎn)生如此大的威力。</p> <p>　　同樣感到意外的不只姜志武,甚至包括負(fù)責(zé)此次爆破工程的廣東宏大爆破公司總經(jīng)理鄭炳旭。讓這位高級爆破工程師“很意外”的是,只使用了3噸炸藥的“小爆破”為何引發(fā)了一場大災(zāi)難。監(jiān)測顯示,此次爆破引發(fā)了2.4級地震。</p> <p>　　事實(shí)上,爆破引發(fā)的飛石早已沖破了事先設(shè)定的200米警戒線,一直飛奔到距爆破中心一公里遠(yuǎn)。即使是距事發(fā)地點(diǎn)大約5公里遠(yuǎn)的大峰礦廠區(qū),亦感受到威力,臨街大多窗戶玻璃被震碎,七零八落,“像剛打完仗一樣”。</p> <p>　　昨日上午,本報(bào)記者實(shí)地踏訪事發(fā)周邊區(qū)域。山被炸開的痕跡白花花地暴露在烈日之下。山腳之下,丁學(xué)聰老漢的院子落滿了“石頭雨”,院子里的碎石整整裝了2車手扶拖拉機(jī),還沒有清理完。他的33間房子被砸毀20余間,老漢欲哭無淚。就在他的鐵板房內(nèi),何老漢被砸破屋頂?shù)氖^砸到腰間,當(dāng)場死亡。大院的外邊,兩顆兩個籃球大小的石頭將堅(jiān)硬的地面砸出兩個深坑。</p> <p>　　<strong>引發(fā)地下殘留炸藥同時爆炸</strong></p> <p>　　廣東宏大爆破公司總經(jīng)理鄭炳旭在接受媒體采訪時表示,爆破方案并沒有考慮到地下的情況。對地下有無盲炮存在,事先并不了解。而據(jù)媒體公開報(bào)道,此前的2007年12月20日,被稱為寧夏和中國煤礦第一爆的硐室爆破工程,在大峰礦羊齒采區(qū)成功爆破。根據(jù)當(dāng)時的爆破方案設(shè)計(jì),該次爆破總面積達(dá)到632.9萬立方米,總裝藥量5500噸炸藥。爆炸當(dāng)量相當(dāng)于日本廣島核爆炸的1/3。</p> <p>　　據(jù)有關(guān)專家介紹,雷管、炸藥的運(yùn)輸和保管必須由具有資格證的專門人員進(jìn)行全程跟蹤管理,但目前不少爆破公司的雷管、炸藥一般讓民工管理,工程爆破后也不對剩余雷管和炸藥進(jìn)行清理入庫,監(jiān)管漏洞百出。因此不少雷管和炸藥被人販賣,進(jìn)而流入社會。</p> <p>　　寧夏自治區(qū)爆破專家劉占武表示,“只有上百噸的炸藥才能造成這樣的爆破。”從現(xiàn)場及圖紙看,產(chǎn)生爆炸的原因很可能是爆破引發(fā)地下殘留的炸藥同時爆炸。</p> <p>　　在現(xiàn)場,一位不愿透露姓名的爆破工告訴記者,為了加強(qiáng)對雷管的管理,有關(guān)部門在雷管上采取了打碼的方式,以便掌握其去向。但不少雷管上的標(biāo)碼被人刮掉,被販賣給不法分子,失去監(jiān)控,令人擔(dān)憂。</p> <p>　　昨日下午,寧夏自治區(qū)政府在大峰礦召開新聞發(fā)布會,向媒體通報(bào)了情況。目前,事故搜救工作已經(jīng)全部結(jié)束,經(jīng)過對事故發(fā)生點(diǎn)1公里范圍區(qū)域4次大規(guī)模、拉網(wǎng)式搜救排查,除已經(jīng)確認(rèn)的16名死亡人員和48名受傷人員外,未再發(fā)現(xiàn)新增傷亡人員。</p> <p>　　有關(guān)方面稱,“10·16”重大事故調(diào)查組對事故原因還在進(jìn)一步調(diào)查。(張鵬慶裕）</div> <div class="49c1n6wlf" id="partner"></div> <div class="49c1n6wlf" id="editor">【<font color=CC0000>編輯:</font>吳歆】</div> <div
