| There are many faults in Weijiadi coal mine. The reserves inside the belt influenced by faults structure are regarded as prospective reserves in the report, the Geologic Report about drilling well in Weijiadi. Meanwhile, because of the influence of the traditional designing ideas, such as short alignment and remaining coal walls etc. The alignment length of all the working faces have always remained at 500 meters or so since the coal mine was opened up.As a result,the development of the coal mine has been limited ,resources has been wasted greatly, and the working faces have to be move frequently.The development of fully-mechanized caving technique qualifies us to reuse these prospective reserves.The industrial experiment in which prospective reserves have been reused with the technique has profound historical significance to the development of the coal mine.Before design of this program , the researchers and engineers in the coal mine obtain the data with detector and by drilling, prospecting tunnel.Then the researchers synthetically analyze the geology data such as the coal seam construction,dip angle,thickness of coal mine.Thus we conclude that the fully-mechanized caving technique can be used in the coal mine.In the process of experiment, We reuse large number of prospective reserves in the working face of "double outburst" and "three soft"coal seam. It is a kind of new safe economic way in reuse prospective reserves. |
