Aim/Purpose: This article aims at the critical present: to serve a constructive purpose in the current COVID-19 crisis by presenting practice driven pedagogical strategies for online learning and teaching. It acknowledges the multitude of challenges faced by educators through the delivery of online instructional strategies for schools. Background: The development of information technology enables online learning and blended learning to be increasingly popular in extending students' learning opportunities. Technology-enabled learning approaches make students' learning more flexible and personalized. In Hong Kong, one of the first few cities where the COVID-19 pandemic outbreak was first reported, school classes have been suspended since the end of Lunar New Year on February 3, 2020. Methodology: This research used a qualitative method of multiple case analysis to explore how three educators from primary, secondary, and tertiary institutes employed various strategies to offer learning and teaching as usual. Naturalistic inquiry was used to observe, describe, and interpret the "lived experiences" of the three educators and the perceptions of stakeholders. Contribution: Since early February 2020, school classes have been suspended amid the COVID-19 pandemic in Hong Kong, one of the first cities where the coronavirus outbreak was first reported. This timely article overviews effective practices with the use of online learning technologies to support academia from around the world to achieve teaching and learning in an online environment. Findings: Results indicate that meaningful cognitive activities rely on teachers' leading role to build a blended approach that combines the advantages of asynchronous and synchronous methods in order to facilitate social interaction among students. Furthermore, our research has revealed that educators are likely to perceive three non-teaching challenges on a rapid blended transition of the learning -- digital divide, data privacy, and professional leadership. Recommendations for Practitioners: The COVID-19 pandemic has disrupted the learning of a generation of students and driven a sudden shift to online learning. Our case study recommends a blended model of asynchronous and synchronous learning as an effective pedagogy that allows learners flexibility, autonomy, and opportunities for learners to socialize with each other, which can be applied at any education level. Impact on Society: Technological advancements have made online classes possible, but how feasible is it to believe that a near overnight transition can lead to effective learning and teaching? The current article strongly acknowledges the multitude of barriers that stand in the way of feasibility, capacity building. and delivery of inclusive online instruction for today's school districts, administrators, curriculum and technology directors, teachers, parents, and students. Future Research: In an effort to generate new knowledge within the challenges of the current pandemic, further studies are suggested to examine the longitudinal impact of these blended approaches, the digital divide, inclusive and accessible learning opportunities of vulnerable groups, and psycho-social support for students towards their academic and social development.

Aimed at the trend of water inrush disasters increasing annually with the mining depth above confined aquifers , based on the conditions of the fully mechanized workface in the deep mine, and according to the in-situ strain value of the mining face at different depth under the coal seam bed, it was determined the coal seam floor failure depth was between 18-20 m. This study analyzed the characteristics of coal seam floor failure through repeated calculations and gradual correction to model boundary conditions, based on the actual formation material in the study area to establish the geological model, which makes up for the disadvantages of coal seam mining stress that the field measurement result could not reflect. The coal seam floor failure depth was 20 m, and it revealed the characteristics of the mine pressure in mining coal floor when combining the in-situ strain measurement method with the numerical simulation method.
