53、有在規(guī)定的時(shí)間和條件下完成指令性功能。結(jié)果使人,機(jī)器或系統(tǒng)環(huán)境在一定程度上蒙受損失。接下來(lái)通過(guò)調(diào)查一些煤礦對(duì)誘導(dǎo)人為錯(cuò)誤發(fā)生的原因進(jìn)行了分析。(1)安全意識(shí)過(guò)于淡薄,工人通常違反規(guī)則行事。(2)工人的性格輕率。(3)生理因素,人類在生理上的一些弱點(diǎn)是人為錯(cuò)誤的根源。(4)心理障礙。(5)工人素質(zhì)較低。(6)疲勞,不尋常的狀態(tài)和其他特殊情況。(7)機(jī)器的缺陷。(8)環(huán)境因素。2.1.2 人為錯(cuò)誤的控制在對(duì)人為錯(cuò)誤原因分析和把握的基礎(chǔ)上,我們可以采取一些措施,以減少人為錯(cuò)誤。第一,應(yīng)建立以人為中心的安全管理制度。其次,在于管理制度的基礎(chǔ)上,它對(duì)人的安全是非常重要的。這些對(duì)策主要包括安全法制教育,安

54、全知識(shí)教育,安全技能教育,安全思想教育,典型事故教育,生物節(jié)律和安全措施。第三,所有的工作都應(yīng)該標(biāo)準(zhǔn)化。第四,應(yīng)大大改善工作環(huán)境。第五,重要的是設(shè)計(jì)良好的界面,減少人為錯(cuò)誤。第六,安全文化應(yīng)該是企業(yè)所倡導(dǎo)的。2.2 人的模糊可靠性分析根據(jù)Hinesburg和Maslow的理論,建立人的模糊可靠性的層次結(jié)構(gòu)圖如圖1。模糊可靠性社交需要自我實(shí)現(xiàn)需要尊重需要安全需要生理需要薪水工作環(huán)境義務(wù)感成功感管理策略福利升遷圖1 人類模糊可靠性的層次結(jié)構(gòu)圖根據(jù)層次分析法2的理論,我們可以計(jì)算衡量Wi各項(xiàng)指標(biāo)。然后我們邀請(qǐng)一些專家來(lái)評(píng)估實(shí)際值Di各項(xiàng)指標(biāo),因此,我們可以用下列公式計(jì)算某一個(gè)或某些群體的模糊可靠性。

55、 (1)作者充分計(jì)算了辛莊煤礦綜采工作面上工人的模糊可靠性。首先,根據(jù)年齡把所有的146名工人分成5組。然后,計(jì)算各組的模糊可靠性。結(jié)果是:0988,0994,0993,0995和099。最后,計(jì)算整個(gè)集團(tuán)的模糊可靠性。結(jié)果是09924。模糊可靠性模型被認(rèn)為是心理因素,生理因素和環(huán)境因素。這使得人在可靠性方面取得了一些進(jìn)展。在這個(gè)模型中也存在一些缺陷。2.3 事故和人為因素之間的關(guān)系2.3.1 煤礦事故與工人素質(zhì)之間的關(guān)系 從1999年至2004年在辛莊煤礦的采煤工作面死亡事故和輕傷事故之間的關(guān)系可以用關(guān)于工人年齡,工齡,文化程度的圖表分析方法中探索。以死亡事故為例,圖2到圖4顯示,隨著年齡的增加采煤工作面的死亡事故減少。隨著工齡的增加,總的趨勢(shì)是文化程度提高。 圖2 死亡人數(shù)的年齡分布 圖3 死亡人數(shù)的工齡分布 圖4 死亡人數(shù)的文化程度分布2.3.2 煤礦事故和疲勞之間的關(guān)系疲勞會(huì)使人的感覺(jué)機(jī)能減弱,它還會(huì)使人的聽力和視力下降,復(fù)雜的刺激的反應(yīng)時(shí)間是比平時(shí)大的,精度是比平時(shí)低的。因此,疲勞對(duì)于煤礦安全生產(chǎn)是十分有害的。采礦工人疲勞的原因主要集中在以下幾個(gè)方面。(1)工作時(shí)間很長(zhǎng),休息時(shí)間不夠。(2)照明,噪聲和任務(wù)空間等環(huán)境因素的影響。(3)高工作強(qiáng)度。(4)非技術(shù)工人。(5)單調(diào)乏味的任務(wù)。(6)一些心理原因。在找出煤礦工作者疲勞原因的基礎(chǔ)上,我們
