1、附录A英文翻译(原文)The Summarized Status Quo Of The Coal And Gas ProminentForecasting Study1 coal and gas prominent mechanismsMechanistic studies on prominent, can be divided into two stages, namely the search for early stage and highlight the factors influencing the recent exploration prominent role proces

2、s stage.(1)The main point of the early scholars are : the role of gas, and stress the role of theory, integrated hypothesis. Integrated hypothesis more comprehensive consideration of a prominent driving force (to stress, and gas) and resistance (coal intensity), the two main factors, and domestic an

3、d foreign scholars generally accepted that if a certain region to stress is greater, gas content (pressure) higher, more soft coal, the region highlight the greater risk. Extraction, located on the prominent, to stress and highlight, gas and coal physical nature of the mechanics of the original valu

4、e of the parameters, is also located near a large extent depends on the parameters of change, namely, located near coal Yan stress, the pressure distribution of gas and coal changes the nature of physical strength. Working side before the greater stress and gas pressure gradient, the less coal inten

Coal and gas prominent from a dist

8、ng body damage occurred Rubian formed fissures net after cross-gas energy washed coal physical damage occurred to highlight the salient points of the extension given a good explanation. Fluid changes hypothesis. Coal and gas are highlighted in a move to contain the impact of coal gas to stress coupl

9、ed with a gas pore gas developments process, in the preparatory phase containing gas coal prominent body damage occurred Rubian formed fissures net after coal gas energy into cross-torn body of prominent, given the perspective of an outstanding good explanation. Secure flow coupled Shiwen hypothesis

10、. Highlight is the body in the coal containing gas extraction activities, the local rapid, sudden destruction generation phenomenon, a deep and the increase in gas pressure will highlight the dangers of the increase. Spheroid shell lose stability hypothesis. The process is to highlight the real stre

Coal physical damage to 42,164 warrants coal shell formation, expansion and Shiwen out for the main character.2 prominent forecasting

12、methods Many prominent scholars about domestic and abroad, through study of the phenomenon and its precursors, have made many prominent forecasting methods that have occurred in the fight against prominent and conspicuous disaster loss reduction has played an important role.(1) Use temperatures fore

13、cast prominent. Coal bed in the highlands of stress (or high stress concentration) and the role of high-pressure gas, and gas adsorption by squeezing out, surrounding rock and coal body temperature to rise; At the same time, coal response to high body gathered for a maximum drilling drilling there,

Tuesday steady through analysis of coal and gas prominent process temperature

15、 changes of the main factors is to stress, pressure and coal gas intensity body, and thus temperature reflects the outstanding combined role, he further discovered through laboratory research, highlighting process, coal body temperature to rise after lowering that body temperature through continuous

16、 observation of coal to achieve outstanding forecasting. Liang ice through numerical simulation results also show that when the temperature gradient changes in the larger, coal and gas will occur outstanding. But some scholars of coal gas as an evaluation body temperature prominent risk indicators argue that drilling temperature and the temperature margin Pik mainly coal mines affected by atmospheric temperature and wind is much for the volume effects.
