Summary: Coal-and-gas outburst (CGO) is a major challenge in coal mining, and the initial gas pressure has a significant influence on the flow characteristics of CGO airflow. The study found that the gas pressure decreases periodically or continuously during the CGO process, and the static pressure in the roadway shows alternating positive-negative pressure transition. The increase in coal seam initial gas pressure leads to higher velocity and longer duration of high-speed airflow in the roadway.

Summary: Flue gas (CO2/N2) injection into coal seam achieves reduction of greenhouse gas emission and enhancement of methane recovery. An improved heat-solid-fluid coupling model is proposed to simulate the interaction between solid deformation, fluid transport, heat conservation, and porosity/permeability. Results show that the proposed model accurately represents the complex interactions and prevents the sharp reduction of permeability caused by pure CO2 injection. The effective extraction zone of flue gas injection expands faster than primary and CO2 promoted extraction, with influencing factors including initial permeability, injection pressure, N2 and CO2 adsorption strain ratio, injection temperature, and thermal expansion coefficient.

Summary: This manuscript outlines a methodological framework for modeling the hydrological impacts of future coal mining and coal seam gas extraction, providing crucial objective information to regulators. The structured uncertainty analysis approach can be applied under a wide range of data availability, and additional data can easily be incorporated to better constrain the results. The methodology has the potential to be adapted and applied to a range of extractive industries, although it currently does not explicitly consider impacts on water quality.

Summary: The crack closure induced by high-pressure air blasting in impact coal seams has a significant impact on gas drainage efficiency. The length of the crack closure was calculated and analyzed using energy and elastic theories, determining it to be 3.8 m from the blasting hole. Field experiments in a Chinese coal mine showed that crack closure led to a decreased gas emission amplitude in the closure region. The theoretical calculations were consistent with the field test results, providing a valuable reference for the arrangement of gas drainage boreholes.

Summary: This study aims to explain the stress evolution law of the upper coal group in the long-distance mining of the lower coal group in Pingdingshan No. 8 Coal Mine. A simulation model was established to study the stress evolution law of the upper coal seam under the influence of advanced mining disturbance of the lower coal seam. The results showed that the advance mining of the lower coal group had both positive and negative impacts on the stress distribution of the upper coal seam group, and the pressure relief effect was remarkable.

Summary: This study aimed to determine the prevalence of alcohol-related presentations in an emergency department using blood ethanol and PEth testing. The results showed that the prevalence of medium-term alcohol consumption was underestimated when only blood ethanol tests were used. The prevalence of alcohol use was higher among patients presenting with injuries. The regular measurement of acute and medium-term alcohol consumption in emergency department presentations would be valuable for targeted public health prevention and control strategies.

Summary: The study aimed to determine whether excluding gestational diabetes mellitus (GDM) based on fasting venous plasma glucose (FVPG) assessment during the COVID-19 pandemic in 2020 had similar perinatal outcomes compared to excluding GDM using the standard oral glucose tolerance test (OGTT) procedure in the previous year. The results showed that the frequencies of most perinatal outcomes were similar for women without GDM in 2019 and those for whom it was excluded in 2020 based on FVPG values. However, there was an increase in the risk of caesarean delivery in 2020 compared to 2019. The probabilities of several outcomes, such as respiratory distress, neonatal intensive care or special nursery admission, and large for gestational age babies, were slightly higher for women without GDM in 2020 compared to women without GDM in 2019.

Summary: The study assessed the trends in birthweight and maternal characteristics over a 19-year period using descriptive statistics. The findings showed a decrease in average birthweight and an increase in large for gestational age births. Maternal factors such as smoking, BMI, and Indigenous status were linked to changes in birthweight and the proportion of small or large for gestational age babies. There was also an increased number of births to older women and a rise in gestational diabetes, but better care practices for women with gestational diabetes resulted in a decline in large for gestational age births.
