In view of the problems occurring in trapezoidal support used in coal seam gateway , a novel small - curvature arch support for mining engineering is presented 摘要针对煤层顺槽梯形支架存在的问题,提出一种新型结构的小曲率拱型支架。
Based on it , the dangerous degree measure ( dangerous believe degree ) was put forward , applied the trained neural network to a few outburst mines engineering verification of huainan diggings 应用训练好的神经网络,对淮南矿区的几个突出矿井进行了工程验证。
Therefore , the investigation on its mechanical properties and fracture process is of a vital importance to mining engineering , underground engineering and engineering 对混凝土材料的力学性质及破坏过程的研究对于结构工程、地下工程以及采矿工程等都有重要的意义。
The applications contains computing mountain x ' s coordinate and the lines of resistance , querying the database of faultage , joint and the information of mining engineering 应用程序包括x山的平面直角坐标和高程求解、抵抗线求解、断层及节理信息查询数据库、工程资料查询数据库等。
The production has made a great success in the reality application in last year and will provide scientific and reliable information for the prospecting mineral resources , mining engineering and computer simulation 这些成果,在一年多的实际工作应用中,取得了圆满的结果,为今后x山资源勘测、开采设计、计算机模拟提供科学的依据。
