2、據(jù)進(jìn)行分析處理，從而確定導(dǎo)致煤層底板突水的主控因素及次級(jí)影響因素，并分別賦予其相應(yīng)的權(quán)重值，將各因素在底板突水中所起的作用定量化。特別是對(duì)于不同礦區(qū)不同控制因素的影響，其相應(yīng)權(quán)重值的大小可以靈活改變。建立賦權(quán)求和數(shù)學(xué)模型，繪制出各個(gè)主要控制因素的專題圖，并根據(jù)各個(gè)主要控制因素的不同權(quán)重值，疊合繪制出底板突水概率指數(shù)法突水分區(qū)圖。同時(shí)計(jì)算出煤層底板突水概率指數(shù)。將系統(tǒng)軟件應(yīng)用于工程實(shí)際，預(yù)測效果與實(shí)際情況相吻合。關(guān)鍵詞：matlab；底板突水預(yù)測系統(tǒng)；突水概率指數(shù)法；權(quán)重；軟件中圖分類號(hào)：TD745文獻(xiàn)標(biāo)識(shí)碼：ADOI：10．3969~．issn．1001．1986．2012．03．010For
