煤與瓦斯突出是煤礦井下嚴重災害之一，而拋出物是災害發(fā)生的直接作用者。
The intermolecular force of deformed coal is relatively small, the deformed coal has low strength and high adsorption capacity, and those determine the outbreak of coal-gas outburst.
構造煤分子間的作用力小，決定了構造煤強度低和吸附性能高，從而控制了煤與瓦斯突出災害的發(fā)生；
The paper researchs the principle of protective seam mining, hydraulic slotting method and executing-digging technology to avoid risk of coal-gas outburst, and its practices in coal mine.
通過分析近距離保護層開采、水力掏槽法及邊抽邊掘技術防治煤與瓦斯突出原理及實踐應用，從而有利于煤與瓦斯突出礦井選擇合理有效的防突技術。
