Talking about technical economy of the coal mine supplemental for the low calorific value refuse heat power plant 煤矿配套低热值矸石热电厂技术经济浅议
Economic operation research of ug75 5 . 3 - m16 type circulation fluidized bed boiler with mixed materials of coal mud and wastes 16型煤泥矸石混烧循环流化床锅炉经济运行探讨
The jiexiu municipal has decided the favorable policy to the enterprise which utilize the waste coal and mid - coal around the city 原材料中煤矸石由市内解决，本市年排中煤矸石
Application of false - inclined flexible shield mining system in coal face with seam pitch less than rest angle of waste 伪斜柔性掩护支架采煤法在煤层倾角小于矸石安息角工作面的应用
Test of grouting and water injecting technology and its application to extinguishing spontaneous combustion of oil shale foundation soil 灌浆注水处理油母页岩矸石地基自燃的试验与应用
This project needs the waste coal and mid - coal 1 . 852 million mts per year which can entirely supplied from 2 - 2 . 5 million mts in the district 万吨，可满足项目矸石中煤185 . 2万吨的需要。
Aimed at the shortcomings of coalface passing through fault as low speed , low efficiency and low - quality coal and so on , a new technique was suggested 摘要针对采煤工作面过断层速度慢、效率低且影响煤质等缺点，提出工作面快速无矸石过断层清洁开采技术。
Based on the rock pressure ' s characteristics of the pre - driven roadway , the rational support plan and parameters about roof bolting with bar and wire mesh are determined , and the manner of driven waste in place of coal was adopted 基于断层中预掘巷的矿压特点，确定出其合理的锚梁网支护方案与支护参数，并采用了掘出的矸石与煤的合理“置换”方式。
We get optimized equation and optimum mixing proportion of all kinds of waste rock concrete ; lastly , we advance to simulate and forecast the compression strength of waste rock high strength concrete and steel fiber high strength concrete by neural network which establish the base for further studying 最后，利用人工神经网络原理，对排矸石高强混凝土和钢纤维高强混凝土的抗压强度进行模拟和预测，为该问题的深入研究奠定了基础。
