矿井系统中水源热泵应用技术探析——以山东省济宁梁宝寺煤矿为例

用水源热泵技术,将矿井回风、矿井水、洗浴废水、冷却水(风)中的低品位废热转变为供热热能。该热泵热回收技术系统可靠、经济效益好,可达到节能减排的目的。该文分析了矿井系统中的废热类型和应用原理,给出了矿井回风、矿井水、洗浴废水、冷却水(风)废热回收量的计算方法,并分析了山东济宁梁宝寺煤矿矿井废热回收供热系统设计实例。认为该技术的应用为矿区提供了生产、生活必备的热源和热水,节约了生产成本,保障了煤矿企业的绿色生产,改善了矿区周围的生活环境。

Primary Study on Constrained Inversion Techniques in Detecting Coal Thickness

Modern mine production technology has gained many achievements. Precision of proved degree of coal strata thickness has become increasingly highly. Through comprehensive utilization geological drilling and well logging and other information, combing with seismic data, a new method with high resolution has formed. It has played respective advantages in drilling, well logging and seismic exploration technology, reduced different technical errors, and extracted the earthquake attribute parameters. Through the wave impedance constrained inversion, coal strata thickness parameters can be gained, and coal strata thickness can be predicated.
