A method for calculating gas permeability of the rock massif depending on its stress-strain state is presented. By using methods of the mine experimental studies, influence of mining operations in the adjacent long walls on intensity of gas release from the previously worked-out long-pillar was determined, as well as impact of the massif stress-strain state on efficiency of the drainage boreholes. Formulas were obtained for calculating coefficients of the impact of zones with static and dynamic abutment pressure on intensity of gas draining in the previously worked-out long-pillar.

AbstractObjectiveA chlorine gas release occurred at a poultry processing plant as a result of an accidental mixing of sodium hypochlorite and an acidic antimicrobial treatment. We evaluated the public health and emergency medical services response and developed and disseminated public health recommendations to limit the impact of future incidents.MethodsWe conducted key informant interviews with the state health department; local fire, emergency medical services, and police departments; county emergency management; and representatives from area hospitals to understand the response mechanisms employed for this incident.ResultsAfter being exposed to an estimated 40-pound chlorine gas release, 170 workers were triaged on the scene and sent to 5 area hospitals. Each hospital redistributed staff or called in extra staff (eg, physicians, nurses, and respiratory therapists) in response to the event. Interviews with hospital staff emphasized the need for improved communication with responders at the scene of a chemical incident.ConclusionsWhile responding, hospitals handled the patient surge without outside assistance because of effective planning, training, and drilling. The investigation highlighted that greater interagency communication can play an important role in ensuring that chemical incident patients are managed and treated in a timely manner.

Abstract The impact of an asteroid or a very large nuclear explosion in the Black Sea may cause a poisonous hydrogen sulfide gas release into the atmosphere. Some effects of this phenomenon on the western Black Sea coasts are evaluated in this paper. Two simple models are proposed to describe the generation of the H2S cloud. The wind speed plays an important role in H2S cloud dynamics. The land surface area covered by the H2S cloud generated by a 1000-m-sized asteroid during the run-in ranges between about 4480 and 9600 km2. This may affect up to 230 000 people. In the case of a 70-m-sized asteroid, the cloud covers between 70 and 210 km2 of land. This may affect between about 1600 and 5100 people. The evaluations do not include the population of the towns on the seashore and may be a few times underestimated for some particular wind directions. These effects are briefly compared with more usual effects associated with asteroids impacting the sea, such as shock waves and tsunamis. Nuclear explosions of 1 and 50 Mton TNT may be assimilated to the impact by asteroids of about 33- and 120-m diameter, respectively.

The impact mechanism of in situ stress on outbursts plays a key role in the prevention of outbursts during deep coal mining. The in situ stress may influence the outburst by affecting the gas release intensity according to theoretical analysis, but none of the existing studies have taken into consideration this perspective. To explore whether the influence of in situ stress on gas release in coal is an important reason for stress-induced outbursts, experiments on gas release in coal under different axial stresses and on exposure-induced outbursts with different gases were conducted to respectively study the influence of in situ stress on gas release and the impact of gas release on outburst. The results show that with the increase of stress, the methane release intensity rises by 1~2.4 times and shows an obvious periodicity due to different degrees of fracture development. A small increase in gas release intensity can lead to huge increase in the outburst intensity based on an energy analysis of the outburst experiments, indicating that the gas release intensity is a sensitive physical quantity that influences outbursts. The differences in gas release in coal with different stresses will result in differences in the outburst results based on data from the two experiments, proving that the change in gas release intensity during variations of in situ stress is an important factor for in situ stress-induced outbursts. The research achievements can enrich the impact mechanism of in situ stress on outbursts.

This paper examines the influence of polyacrylamide on soil biological activity. The results of the incubation experiment conducted in the laboratory are given. Carbon dioxide gas release or soil respiration is- one of the indicators of soil biological activity. Determination of the amount of released CO2 was carried out titrimetrically. Aliquots of alkali titrated continuously throughout the experiment. The graph presents the resulting effect of introducing polyacrylamide into the soil on release of total CO2. Finally the article presents conclusions and puts the problems of further study and system analysis of application of polya-crylamide in the active soil environment.

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.
