查询词典 opencast mining

Rock mass deformation and failure in working face caused by underground mining lead to mining-induced fracture, which is the source of a series of mine disasters. The research on geophysical characteristics of mining-induced fracture rock mass and feasible geophysical techniques with high accuracy and resolution detection on mining-induced fracture rock mass are meaningful theoretically and practically for the safety of coal mines and the prevention of mining disasters.

Thissubject exerts the experiment method of analogue modeling, and we take geologic mining condition of the Xin Zhi Colliery of Huo Zhou Mineral Bureau in Shang Xi province as the physical model of background design. The experiment is divided into two phases, the first phase simulates the course of mining subsidence, we study rule of movement transmogrification of mining terrane. In the second phase, after the mining subsidence is gradually stabilization, we bring into bear different load in the different location of subsiding basin, and we study ground stability with goaf.

本课题以山西霍州矿物局辛置煤矿地质采矿条件为例，进行了相似材料模拟试验，试验分为两个阶段：第一阶段模拟开采沉陷过程，研究采动岩层移动变形规律；第二阶段在开采沉陷基本稳定之后，在沉陷盆地的不同位置施加大小不同的建筑物荷载，研究其地基的稳定性。

Image mining is the important branch of data mining.It is more than just an extension of data mining to image domain but an interdisciplinary endeavor.Image clustering and similarity retrieval are two basilic parts of image mining.
