我国煤炭资源丰富,但“三下”压煤也十分严重.特别是村庄建筑物下压煤,目前严重影响着煤矿企业的正常生产,威胁着矿井的寿命.村庄下采煤已成为“三下”采煤的工作重点,是我国“七五”期间急待研究和解决的生产关键问题之一.条带法开采中,采留宽度合理尺寸的确定是条采设计的首要任务,也是涉及到条采成败的关键问题.对条带采留宽度尺寸的确定,国内外开采实践已积累了丰富的经验〔2〕,许多从事“三下”采煤和岩石力学的有关学者也对此作了大量的研究,取得了一定的成果. In our country, there are abundant coal resources, but the “three times” pressing coal is very serious, especially under the pressure of village buildings, which has seriously affected the normal production of coal mines and threatens the life of the mines. “The focus of coal mining is one of the key production issues urgently needed to be researched and solved in China during the” Seventh Five-Year Plan. “In the strip mining, the determination of the reasonable size of the collection width is the primary task of the mining design and involves The key issue of the success or failure of strip mining is to confirm the width and width of strip mining and the rich experience has been accumulated in domestic and overseas mining practices.2 Many scholars engaged in ”three times" coal mining and rock mechanics also made this A lot of research, and achieved some results.
