Closure of gate roads with soft floor is a problem encountered in the carboniferous coal measures of the North America and Europe.

关闭大门的道路软底是一个问题中遇到的石炭纪煤系的北美和欧洲市场。

Introduction Closure of gate roads with soft floor is a problem encountered in the carboniferous coal measures of the North America and Europe.

导言 关闭大门的道路软底是一个问题中遇到的石炭纪煤系的北美和欧洲市场。

It is proved by experiments that the expansion energy of initial releasing gas and the thickness of soft coal seam can be used to forecast outburst accurately under the condition of "uncovering ideal crosscut".

实验证明，采用初始释放瓦斯膨胀能和软煤厚度可以准确地预测理想石门揭煤条件下的突出危险性。

Its crushing performance can only meet the crushing requirements for the coal and the softer declaim nation so that the application is restricted and the mine application requirements can not be met .

其破碎性能仅能满足煤及较软剥离物的破碎，使用受到了限制，不能满足矿山使用要求。

During treatment of soft soil subgrade located in large regional fault zone, model of floating bridge above water is adopted. Based on characteristics of subgrade soil with large porosity and loose, consolidation grouting method is used to raise load capacity of subgrade which can combine underground reinforced concrete raft foundation with steel pipe friction micropile to improve integrity strength of special heavy traffic soil subgrade.

摘要］ 阐述在区域性大型断层带的软基处理中运用"水上浮桥"的建模思维方式，根据路基岩土体孔隙率大、松散的特点，采用固结灌浆从挖掘岩土体本身的潜力提高地基承载力，固结灌浆岩土体使准连续配筋混凝土地下筏板基础与摩擦型钢管微桩有机结合，以此提高运煤特重交通路基的整体强度。

And proposes that f value is regarded as the classification quota of hard coal and tectonic soft coal.

并提出将f值作为硬煤和构造软煤的分类指标。

The using result of shearer helical drum used in three soft coal seam is analyzed,and in order to improve the coal-loading capability,some theory analyses and reference opinions are provided at the same time.

分析了采煤机螺旋滚筒在三软煤层中的使用效果，为在三软煤层中滚筒如何能提高装煤效果提供了理论分析和参考意

It is narotic and toxic, obtained when soft coal is heated in the absence of air, used as a medium for carrying gravure inks.

它具麻醉性和有毒。是软煤在无空气下加热生成。用作凹版印刷油墨的介质。

The kaolinitic tonsteins, the kaolinitic rocks not adjacent to coals and soft kaolin were studied in this project. The studies show that the materials forming the kaolinite come from the volcano ashies, terrigenous transportation and the solution precipitation of the rocks surrounding the weathering coals.

本项目对我国煤系夹矸高岭岩、煤层不相邻高岭岩和煤系软质高岭土进行了详细研究，认为成矿物质主要来源于火山灰、陆源搬运产物以及煤层围岩物质的溶解沉淀。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
