Research Progress And Thinking On Integrated Tunneling And Detection Technology Of Rock Roadway With Tbm, Yuan Liang, Zhang Pingsong Mar 2023

Research Progress And Thinking On Integrated Tunneling And Detection Technology Of Rock Roadway With Tbm, Yuan Liang, Zhang Pingsong

Coal Geology & Exploration

The construction of Full Face Tunnel Boring Machine (TBM) in coal mines is crucial for achieving efficient and modern high-intensity development and mining operations. However, TBM has poor adaptability to adverse geological conditions, such as fracture zones, faults, soft rock layers, and water-rich areas, which can cause problems such as collapses, equipment sticking, and water gushing, hindering their development. To fully utilize the rapid tunneling efficiency of TBM, integrated design between advanced detection instruments and TBM must be performed. The key technology is the breakthrough in detection-while-tunneling. This paper reviews recent advancements in the integrated tunneling and detection technology of …


Status And Advance Of Seismic Diffraction Exploration In Coalfield, Peng Suping, Zhao Jingtao, Sheng Tongjie, Yang Jie, Tao Junhong Mar 2023

Status And Advance Of Seismic Diffraction Exploration In Coalfield, Peng Suping, Zhao Jingtao, Sheng Tongjie, Yang Jie, Tao Junhong

Coal Geology & Exploration

In China, there is an urgent need for intelligent and environmentally friendly coal mining practices to address the issue of accurately mapping transparent geological conditions, including coal rock structures, water-bearing bodies, goafs, and underground stress. These hidden disaster-causing bodies are prone to triggering mine accidents such as water inrush or gas outburst, which is the main obstacle to safe and intelligent coal mining. Three-dimensional seismic exploration is the main technology for detecting geological bodies such as faults and collapse columns. However, this technology, based on the framework of reflection theory, faces challenges in detecting small-drop faults and small-scale collapse columns. …

Analysis And Jet Drilling Test Of Coiled Tubing Drilling String For Underground Coal Mine, Yao Ningping, Wang Li, Zhang Jinbao, Dou Xuqian, Wei Hongchao

Coal Geology & Exploration

Due to continuous tripping, uninterrupted circulation and other technical advantages, coiled tubing drilling has become one of the fastest developing oil-drilling-technologies in recent years. Developing the coiled tubing drilling technology for underground coal mine is an essential technical means to realize “less humanized” or even “unhumanized” coal drilling. Aiming at solving the key problems existing in the application of this technology in underground coal mine, such as pipe string optimization and drilling method, the coiled tubing jet directional drilling method was proposed. According to the mud pump capacity and borehole depth design for underground coal mine drilling, the fluid friction …

The Effect Of Magnet Hospitals On Nursing Burnout, Jonathan Settle, Michael Davis, Eric Pulice, Alberto Coustasse Mar 2023

The Effect Of Magnet Hospitals On Nursing Burnout, Jonathan Settle, Michael Davis, Eric Pulice, Alberto Coustasse

Management Faculty Research

Introduction:

The World Health Organization [2019] defined burnout as a syndrome caused by chronic job stressors that are not successfully managed, characterized by exhaustion, depersonalization, job detachment, and feelings of inadequacy (WHO, 2019). According to Murthy [2022], the nursing burnout crisis was underway before COVID-19. Nurse burnout recognized pre-COVID-19 was due to systemic organizational problems such as inadequate organizational support and underinvestment in public health (Murthy, 2022).

A 2022 survey of 2500 nurses exhibited increased rates of burnout during the pandemic, with 75% of respondents experiencing burnout, while 65% of those surveyed expressed their desire to leave the healthcare field …

What Do Pet Owners Believe About Dog And Cat Emotions?, Harold Herzog

Herzog - Companion Animal Issues

While some philosophers disagree, most dog and cat owners know their pets experience emotions. Researchers recently asked pet owners about the number and types of emotions they observed in their cats and dogs. There were significant individual differences in the degree to which owners thought their pets experienced emotions.


Death Rates From Alzheimers, Wesley Gerndt, Ainsley Ambrose Mar 2023

Death Rates From Alzheimers, Wesley Gerndt, Ainsley Ambrose

[Archive] Belmont University Research Symposium (BURS)

Since 1999, Alzheimer’s disease has become more of a talking point in our society. This could be because death by Alzheimer’s disease has increased gradually over the years in the United States (NCHS, 2022). We hypothesized that mortality rates due to Alzheimer’s disease will increase as life expectancy rises. This is due to the fact that individuals under the age of fifty-five are highly unlikely to develop this disease. The dataset we examined and analyzed, Leading Causes of Death, comes from the National Center for Health Statistics and showcases the causes of death in each state in America from 1999 …
