辽宁省朝阳市一花岗岩矿山为全晶质结构斑状辉绿岩 ,晶粒细而均匀 ,构造紧密 ,抗压强度达 1 50ＭＰａ,吸水率小于1 % ,肖氏硬度为 85.8。该矿总储量为 357万ｍ3 ,现已开采2 60万ｍ3 ,由于出材率较低 ,积存了 1 90万ｍ3 废料。这些废料不仅占用了大量土地 ,而且废料经雨雪淋湿的 A granite mine in Chaoyang City, Liaoning Province is an all-crystalline porphyrite-type diabase with fine and uniform grains and compact structure with a compressive strength of 150 MPa, a water absorption of less than 1% and a Shore hardness of 85.8. The total reserves of the mine is 3.57 million m3, with 2.6 million m3 already mined. Due to its low output, 1.9 million m3 of wastes have been accumulated. These wastes not only take up a lot of land, but also the waste gets wet by rain and snow
