Great harm because gas accidents and eliminate hidden perils of gas takes more time and cost, and the threat of gas disasters have also greatly limits the scale of coal production, productivity and economic efficiency. Effective control of gas disaster is to ensure sustainable development of China39。由于瓦斯事故的危害極大，消除瓦斯事故隱患需要花費(fèi)較多的時(shí)間和費(fèi)用，而瓦斯災(zāi)害事故的威脅也極大限制了煤礦生產(chǎn)規(guī)模，生產(chǎn)效率和經(jīng)濟(jì)效率的提高。瓦斯災(zāi)害的有效控制是保證我國(guó)煤炭工業(yè)可持續(xù)發(fā)展的一個(gè)關(guān)鍵性問題。s coal industry is a key issue.Pingmei Minmetals had eight mining area in gas tank design uses a play up and down along the bedding parallel to nonpallel boring, and high level borehole in gob drainage pipe, drainage in the upper corner of a bination of gas drainage method , he can ensure that the excavation work under the conditions of low gas content of the work, to create a safe working environment for mining, pumping gas costs are relatively low.According to Minmetals had eight mining areas Pingmei all the information of the rational design of bination of gas drainage, process parameters, such as drainage effect evaluation technology is necessary, be able to mine gas drainage and scientific management, production planning the scientific establishment and strict implementation of plans to provide the necessary scientific basis, but also ensure safety in production, improve efficiency and effective means of production efficiency.Keywords：gas drainage ； nonpallel boring； high level
