1) Weichang
围场
1.
Mineralogy Research on Mulan Stone from Weichang County,Hebei Province;
河北围场木兰石矿物学研究
2.
Based on discussion the history of environmental change,situation of environmental degradation and the reasons by the case dtudy of Weichang in Hebei province,this paper analyzed the important problems existed in eco|environmental control.
本文以河北省围场县为例 ,在论述了其环境演变历史、退化现状及动因后 ,对当前突出的生态环境治理问题进行了分析 ,并提出了生态环境治理的原则与对策 。
2) surrounding rock
采场围岩
1.
Effect of longwall length on mechanical characteristics of surrounding rock stress shell in mining face;
采场围岩应力壳力学特征的工作面长度效应
2.
Numerical simulation-FLAC~(3D) and equivalent material simulation were carried out to analyze the distribution of surrounding rock stress with different thick coal seams based on engineering geology and exploitation technology of 1151(3) fully mechanized top-coal caving(FMTC) face in Xieqiao colliery.
以谢桥矿1151(3)综放工作面工程地质和开采技术条件为背景,应用实验室相似材料模拟和计算机数值模拟(FLAC3D),对不同煤层厚度采场围岩应力分布规律进行系统的分析和研究,获得了采场围岩宏观应力壳力学特点和变化规律,即随开采煤厚的增大,应力壳的几何高度增加,壳基应力降低,分布范围增大且离工作面煤壁越远;揭示了煤层厚度对该力学特征的影响和综放与综采工作面及围岩宏观应力壳力学特征的差异,也正是综放工作面矿压显现不同于综采工作面的根本所在。
