Statistics has it that coal refuses discarded every year through our coal mines amount to approximate 7 million tons,some 3 to 4 hundred tons piled on each coal mine.Recent years have witnessed the ever-in-creasing problems of environmental pollutions such as stream pollution,forest damage,and public nuisances,which are allegedly caused by coal refuses.
In this regard, a few people interested are quite worried about the continual collapse of mining businesses. This we are able to attribute to the industrial rationalization policy of the government during 1990's.
Here we consider that the radical method of mass consumption of coal refuses lies in the good use of them as construction materials. This,we are sure,will enable us to clear up a difficult problem of gathering aggregate,to expect to obtain the result of curtailment of expenditure in exploiting the coal mines with the rise-up of added value,and also to make activated community development of coal mine areas which are still stagnant,and also to better the environment in terms of the proper use of refuses.
Thus we attempt to investigate the geotechnical characteristics of coal refuses, examining the possibility of the improvement method of soft soil for the strength increase.
