摘要
鄂尔多斯盆地D气田存在大量天然气、煤炭、煤层气等资源,叠置区多矿种资源交叉开采存在一定的相互影响。以D气田气煤叠置区为研究背景,分别采用事件树、JSA和Bow-tie模型等方法对叠置区交叉开采进行危害识别和风险分析,确定了矿井透水、油气田火灾爆炸、天然气泄漏和人员中毒4类安全风险;同时,根据风险分析结果对提出的气煤协调开采3种模式进行安全技术对比,确定气煤协调同采模式为统筹2种资源安全开采的最优技术方案。
There are a lot of mineral resources such as natural gas, coal and coalbed gas in an area of a certain gas field in Ordos Basin, which has interaction for cross mining in superimposed area. Taking the superimposed area in a certain gas field as the background, this paper studied hazard identification and risk analysis by using event tree analysis, job safety analysis and Bow-tie analysis respectively, with 4 kinds of risks being determined, including mine water disaster, fire and explosion, natural gas leakage and person intoxication;then compared these three technical schemes through risk analysis, and determined coordinated co-mining was the optimal technology scheme to mine the two resources in safety.
