Relating Detonation Parameters To The Detonation Synthesis Of Silicon Carbide, Martin Langenderfer, Eric W. Bohannan, Jeremy Lee Watts, William Fahrenholtz, Catherine E. Johnson May 2022

Relating Detonation Parameters To The Detonation Synthesis Of Silicon Carbide, Martin Langenderfer, Eric W. Bohannan, Jeremy Lee Watts, William Fahrenholtz, Catherine E. Johnson

Chemistry Faculty Research & Creative Works

Detonation synthesis of silicon carbide (SiC) nanoparticles from carbon liberated by negatively oxygen balanced explosives was evaluated in a 23 factorial design to determine the effects of three categorical experimental factors: (1) cyclotrimethylene-trinitramine (RDX)/2,4,6-trinitrotoluene (TNT) ratio, (2) silicon (Si) additive concentration, and (3) Si particle size. These factors were evaluated at low and high levels as they relate to the detonation performance of the explosive and the solid Si-containing phases produced. Detonation velocity and Chapman-Jouguet (C-J) detonation pressure, which were measured using rate stick plate dent tests, were evaluated. Solid detonation product mass, silicon carbide product concentration, and residual silicon …


Present Situation And Prospects Of Tourism Resource Evaluation In Abandoned Mining Areas, Wang Qiuju, Wang Yue, Ma Yuying, Zhang Bo Apr 2022

Present Situation And Prospects Of Tourism Resource Evaluation In Abandoned Mining Areas, Wang Qiuju, Wang Yue, Ma Yuying, Zhang Bo

Coal Geology & Exploration

The identification and evaluation of tourism resources are important basis for tourism planning and development in abandoned mining areas. This paper adopts literature review method and inductive analysis method to comprehensively sort out the domestic and foreign research results on the value evaluation of tourism resources in abandoned mining areas, and systematically analyze the identification, evaluation system construction and evaluation methods of tourism resources in abandoned mining areas. It is found that the current understanding of tourism resources in abandoned mining areas is only at the level of mining relics and mining heritage, lacking emphasis on the natural resources such …


Principle Of A Self-Protective Sealing Device For Mwd And Its Influencing Factors, Wang Yaoming, Ye Genfei, Zhao Yongzhe, Gao Ke, Liu Weiwei, Duan Huijun Apr 2022

Principle Of A Self-Protective Sealing Device For Mwd And Its Influencing Factors, Wang Yaoming, Ye Genfei, Zhao Yongzhe, Gao Ke, Liu Weiwei, Duan Huijun

Coal Geology & Exploration

For deeper drilling depth and longer service life of MWD, a self-protection sealing device for the MWD instrument is designed given the defects of the combined static sealing structure. The relationship between rubber airbag expansion displacement and air pressure was studied through static expansion numerical simulation. On this basis, the reasons for different results due to different model sizes were analyzed, and the factors causing the different simulation results of the self-protection sealing device were discussed. The four independent variables of airbag diameter, width, wall thickness and inner cavity width were determined and simulated to explore their relationship with the …


Establishment Of A 3d Solid Model Blasting Rock Mass Based On Intelligent Lithology Identification, Chen Yingxian, Wang Pengfei Apr 2022

Establishment Of A 3d Solid Model Blasting Rock Mass Based On Intelligent Lithology Identification, Chen Yingxian, Wang Pengfei

Coal Geology & Exploration

With the development and application of intelligent drilling machine, the lithology data of blasting borehole can be obtained accurately. The blast-hole database is established to store and manage the intelligently identified blast-hole data. Taking the rock property data of blast hole as the sample, the inverse distance square method is used to interpolate the solid elements within the blasting area to generate the 3D solid model of blasting rock mass. The 3D solid model of rock mass was cut by using the polygon of blasting area and the triangular network of bench, and then the 3D solid model of blasting …


Establishment And Application Of Four Basic Data Accounts For Coal Mine Water Control, Lyu Yuguang, Li Mingzhen, Hu Falun, Liu Shuang Apr 2022

Establishment And Application Of Four Basic Data Accounts For Coal Mine Water Control, Lyu Yuguang, Li Mingzhen, Hu Falun, Liu Shuang

Coal Geology & Exploration

Mine water inflow, aquifer water level, analysis data of water quality and formation information are closely related to water prevention and control. It takes a long time to collect a large amount of data. The relevant technical specifications clearly require the establishment of an account for data management, but there is no unified and practical account format, and detailed description of its purpose. Microsoft Excel is used to establish four basic data accounts of mine water inflow, aquifer water level, hydrochemistry and information on stratum. The format of the account is standardized, and the methods for data application of each …


Formation Of Permafrost And Its Influence On Natural Gas Hydrate Accumulation In Muli Region, Qinghai Province, Wang Liping, Zhu Yinghao, Li Ning, Xu Shuanhai, Tian Yanzhe, Liu Naifei, Wang Wenli Apr 2022

Formation Of Permafrost And Its Influence On Natural Gas Hydrate Accumulation In Muli Region, Qinghai Province, Wang Liping, Zhu Yinghao, Li Ning, Xu Shuanhai, Tian Yanzhe, Liu Naifei, Wang Wenli

Coal Geology & Exploration

The characteristics of the existing permafrost and natural gas hydrates were summarized and analyzed by studying the natural gas hydrate formation in Muli Region, Qinghai Province. On the basis of the evidence of the Quaternary climate survey and the available geological exploration data on the Qinghai-Tibet Plateau, FLAC3D was used to simulate and calculate the formation of permafrost. The calculation results show that the existing permafrost probably formed during the late Holocene Neoglacial(4 000-3 000 to 1 000 a BP), and a stable boundary at bottom of the permafrost layer formed after about 170 a of cooling at a …
