Ethylene - propylene rubber insulated high - voltage shielded soft cable with cold - resistant sheath working condition for soft rubber mine cable is difficult , experiencing frequent curve smash of stone and coal pressure of different machine detonable gas , its structure has following features 矿用橡软电缆的工作条件十分苛刻，它在使用中要经受频繁的弯曲，矸石和煤块的冲砸，各种机械的刮碰和挤压，以及矿井中有易爆的瓦斯气体，因此矿用电缆的结构有如下特点：
Firstly , the environment harm of the waste rock is studied ; secondly , we research the physics and mechanics property of the waste rock of the dabagou tunnel and get the physics and mechanics property index of waste rock ; thirdly , after comminuting the waste rock and compounding concrete as coarse aggregate , we make the comparison between it and the songshan stone in the fuxin building market at present , it proves to possess extension application value ; fourthly , on the foundation of it , we utilize waste rock as coarse aggregate to compound high strength concrete , steel fiber high strength concrete , polymer cement concrete , asphalt concrete by uniform design and research their mechanics property index by experiment 首先阐述了排矸石对环境产生的危害，其次对大巴沟隧道排矸石的物理力学性质进行了试验研究，获得了排矸石的物理力学性能指标。将排矸石粉碎后，作为粗骨料配制成混凝土，与目前阜新建筑市场上所用的松山石子进行比较，证明其具有推广应用价值。在此基础上，利用均匀设计法，将排矸石作为粗骨料配制成高强混凝土，钢纤维高强混凝土，聚合物水泥混凝土，沥青混凝土，通过试验测定其力学指标，获得了各种排矸石混凝土的优化方程和最佳配合比。
The activatory coal gangue powder ( acgp ) , ground cement clinker and natural gypsum are mixed by different ratios to prepare blended cement specimens , and its mortar compressive strength performance , water usage for standard consistency , and flowability of mortar are investigated 摘要将经燃烧等过程进行活化处理的煤矸石细粉与磨至一定比表面积的水泥熟料及天然生石膏混合均匀，制成了活化谋矸石粉掺量比例不同的多组混合水泥，并对其胶砂强度性能、标准稠度用水量、胶砂流动度进行了实验检测。
Taking coal wasting lands of yanzhou mining group as an example , treated coal wasting piles was analysed and from elological point of view a tentative programme was put forward for follow - up improvement to set up a model for in coal wasting lands and other similar areas landscape restoration 文章以兖州市充州矿业集团矸石废弃地为例，对已改造的矸石山进行分析，从景观生态学角度为后续该地区景观恢复的改进提出初步方案，旨在从另外一个角度使用“斑块廊道基质”为框架指导矸石废弃地景观改造，从而为其他地区的废弃地景观恢复与改造提供一定的参考。
