The authors discuss the problem connected with insulation of exposed rock surface areas against the aggressive influence of mine atmosphere and rock falls during mining. The lab-scale tests determine the moisture effect on the strength of rocks in the Orlov Ore Field. The tensile strength of samples of isolation membrane as well as their adhesion to rocks and shotcrete is assessed. The technology of preparation and application of polymer membrane insulation layer on the surface of differently damaged areas on the roof and sidewalls in stopes is justified for the Orlov Mine.

抗矿井大气影响的裸露岩面保温技术

作者讨论了与暴露的岩石表面区域的绝缘有关的问题，以防止采矿过程中矿井大气和岩石坠落的侵蚀性影响。实验室规模的测试确定了水分对奥尔洛夫矿场岩石强度的影响。评估隔离膜样品的拉伸强度以及它们对岩石和喷射混凝土的粘附。在采场顶板和侧壁不同损伤区域表面制备和应用聚合物膜绝缘层的技术对于奥尔洛夫矿来说是合理的。
