Authors: Zhang Zhen Guo , Liu Chang Shui , Gao Lian Feng , Zhang Ying , Shi Guo Yuan , Zhang Peng
Published: June 2012

Polymetallic nodules are one of the most important sedimentary mineral resources in the ocean, in which iron, manganese, copper, cobalt, nickel and other metals are rich, and rare earth elements are rich, too. The samples are collected from the northwest continental margin of South China Sea (SCS). Their model show the similar appearance to the oceanic nodules which collected from the Pacific and Indian Ocean. They are big, regular shape and clear layers. But their geochemical characteristics show distinct difference with oceanic nodules.The samples formed by multiple millimeter-thick layers of Fe and Mn oxyhydroxides surrounding the nucleus composed of plastic marl and sediment. Massive, laminated, detrital and mottled to dendritic textural features were developed by the Fe and Mn oxyhydroxide layers.Based on the detailed study of the geochemistry and growth rate, the nodules may represent new-type ones which grow fastly in high sediment rates environment from the northwest continental margin of the SCS. The reason of the fast growth may be affected by the environmental fluctuations and the change of terrigenous sediments. Elements correlation of Mn-Fe-(Cu+Ni) suggests that the origin of the sample may be of hydrogenic. It may be show that these nodules are dominative of the special environment of the marginal sea which includes the geographical condition and the oceanic environmental factors. The average content of Rare Earth Elements (REEs) in these samples are much higher than those recorded in Earth’ crust and sedimentary rocks. The enrichment of rare earth elements is controlled by iron and manganese oxides and clay minerals in nodules, which could absorb rare earth elements from seawater and terrigenous sediment. Ce elements are highly enriched, making polymetallic nodules become the first used rare earth elements in oceanic mineral development.

Coal and gas outburst is a strong dynamic phenomenon in the process of coal mining, which the fierce degree and destroy effect is beyond imagination, also can cause the occurrence of secondary disasters, such as fire, gas explosion. Especially in coal roadway excavation face, it is frequent. Therefore, the reasonable prediction and evaluation for associated factors of coal and gas outburst in coal roadway excavation working face is important and guiding significant for coal production, sustained and healthy development. With the mathematical model of grey synthetically relational degree analysis, we gain quantitative analysis of six prediction indexes of coal and gas outburst, and determine the best predictors, provide quantitative basis for the selection of coal and gas outburst prediction indexes.

Coal is one of the non-renewable resources, and in our country at present also is the main source of energy. It is very important to improve the coal mining rate, to exploit and to use the coal reasonably. Saving coal resource is an important measure for our coal industries sustainable development. Because large amounts of coal under complex conditions caused by fully mechanized mining can not be mined, the rotation mining with large angle for unequal and fully mechanized mining face and its design and main parameters are introduced in this article based on an engineering practice. Using this mining method, the coal under complex condition can be mined as much as possible. It is helpful for us to improve coal mining rate and to economize coal resources.
Retaining a Goaf-Edge Gateroad in a Three-Entry Panel Layout
Authors: Xue Jun Hua , Xue Sheng
Published: June 2012

In underground coal mining, a goaf-edge gateroad (GEG) in a longwall panel is often retained in full length, i.e. the length of the retained GEG is the same as the length of longwall block, for ventilation and gas control. In some cases, it can be extremely difficult to retain a GEG in its full length due to complex geological and geotechnical conditions. To address the issue, the concept of retaining a GEG in sections is introduced. The retained length of a GEG is optimised through the analysis of the inner and outer structures of surrounding rocks of the GEG. Retaining a GEG in sections avoids the intensive roof movement period and possible structural failure of its support. This method of retaining a GEG in sections was successfully applied in panel 24202 of Shaqu coal mine.

Published: June 2012

The collapse of the hard roof rocks was characterized by its sudden and entire breakage and falling during the mining of the shallow-thick coal seams in Datong district. In this paper, structural mechanics methods was used to study the collapse mechanism of the hard roof rocks. The results showed that when some of the coal pillars lost their load bearing capacity, the pressure of the surronding rocks would be transferred to the left ones which were also to be damaged due to the extra load, and this would cause a domino effect of the adjacent pillars’s failure, and eventually cause the entire collapse of the hard roof rocks.

Longtime existence of the mined-out region brings enormous security potential risk to the residents living in ore area. The model of the mined-out region underground has been established and calculated, and the effect of mined-out region on ground subsidence has been analyzed. The analysis result shows that the deformation of the roof of the mined-out region has significant influence on the ground surface and measures must be carried out immediately. Finally, the rational measures for treating the mined-out region are given to ensure the smooth and safe operation of the follow-up mining.

Published: June 2012

Yanglin’ao tungsten deposit is a typical mesothermal to hyperthermal filling-metasomatism postmagmatic deposit. It is featured with the structure-controlling distribution of ore-body and mineralization; while veinlet-type ore-bodies are particularly situated at the hanging wall of F24(No.24 of Fault Fracture), and the mineralization is especially concentrated below and above the unconformable surface between Proterozoic Banxi slate group and Middle DevonianYanglin’ao sandstone formation. Geological characteristics, structure forms and its formation mechanisms of ore-controlling structure were studied in this paper and a special tectonic-controlled model was initially set up. Furthermore the author also made mineralization prospecting prediction based on structure characteristics.
