在苏联和国外的矿井建筑中,使用人造材料(例如胶乳沥青)护板,用以提高井筒支护的防水能力。但是,多次观察表明,这些材料不能保证该结构必要的防水性。使用它们,涌入井筒中的水仍然达0.5m~3/min. 此外,象混凝土这样的矿山巷道的传统支护材料,使用中已经达到了最大强度极限,所以,必须寻求新材料。 波兰和其它国家对用聚合物浸润过的沥青混凝土(PC)和水泥混凝土(PIC)研究的良好结果认为,采用它们可以改善矿山巷道支护的防水能力和强度性能。
In mine buildings in Soviet Union and abroad, man-made materials (such as latex asphalt) are used to improve the waterproof capacity of wellbore support. However, many observations have shown that these materials do not guarantee the necessary water resistance of the structure. Using them, the influx of water into the wellbore still reaches 0.5m~3/min. In addition, traditional support materials such as concrete mine roadway have reached the maximum strength limit in use, so new materials must be sought. Poland and other countries have studied the good results of polymer-infiltrated asphalt concrete (PC) and cement concrete (PIC). They believe that using them can improve the waterproof capacity and strength performance of mine roadway support.
