地下矿产开采对天然气管道工程的安全影响评价

Safety Evaluation of Gas Pipeline Engineer Effected by Underground Mineral Resource Exploration

西气东输天然气管道工程途经兖州市,穿越杨庄、杨村、兴隆庄等煤矿矿区,压覆煤层埋深变化较大。该文采用预测法对各煤矿在不同开采条件下分煤层对管道运营安全的危害程度进行了评价分析。通过计算表明,煤矿开采埋深越浅,煤层越厚,对管道危害越严重。兴隆庄煤矿3煤层、杨村煤矿煤16上、煤17开采对管道影响强烈,杨庄煤矿煤16上、煤17开采对管道影响中等,兴隆庄煤矿煤16上、煤17开采对管道运营影响小。

The project which transports gas from west to east China will pass through Yangzhuang, Yangcun, Xinglongzhuang coal mines in Yanzhou city, and the depth of coal strata vary greatly. By using predication method, damge degree of gas pipe lines in different conditions are evaluated in this paper. As showed by the calculation result, the shallower and deeper of the coal mining, the more serious the pipe is damaged. The third coal stratum, the upper part of the sixteenth coal stratum and the seventeenth coal strata will effect pipeline strongly. The upper part of the sixteenth coal stratum and the seventeenth coal strata of Yangzhuang coal mine will effect pipeline in medium degree, and the upper part of the sixteenth coal stratum and the seventeenth coal stratum of Xinglongzhuang coal mine will effect pipelines in small degree.
