豫西——黄河以南,京广铁路以西,平顶山以北的河南境内,煤炭储量丰富,质地优良,又地处中原,交通方便,为我国近期煤炭资源开发的重点之一。 由于成煤条件和构造运动的影响,豫西二迭系山西组主采煤层二_1煤煤层厚度从0～37.78米之间相间变化,平均厚度5.35米,属不稳定煤层且煤质松软易碎,呈粉状,给今后重点大规模开发豫西煤炭带来了很大困难。 河南省煤炭学会针对上述问题,于84年10月11日至13日在郑州召开了豫西松软不稳定厚煤层采煤方法讨论会。省内有关生产、科研、设计等单位共六十多人参加了会议。同时还邀请了省外有关高等院校、科研、生产等单位的专家、学者到会献计献策,交流经验。河南省煤炭厅总工程师、河南煤炭学会理事长严金满同志主持会议,河南煤炭学会常务理事、开采专业委员会主任委员崔
West Henan - south of the Yellow River, west of Jing-Guang Railroad, Henan Province north of Pingdingshan, has abundant coal reserves, good quality and convenient transportation. It is one of the focuses of coal resource development in recent years in China. Due to the conditions of coal formation and tectonic movement, the coal seam thickness of main coal seam 2_1 of Permian Shanxi Formation in the west of Henan Province varied from 0 to 37.78 m with an average thickness of 5.35 m. It is an unstable coal seam and the coal quality is soft Fragile, powdery, to the future focus on large-scale development of western Henan coal has brought great difficulties. In response to the above problems, Henan Coal Institute held a symposium on the mining method of soft and unstable thick seam in the west of Henan Province from October 11 to November 13, A total of more than 60 people from production, scientific research and design units attended the meeting in the province. At the same time, experts and scholars from institutions of higher learning, research and production outside the province are also invited to give advice and exchange ideas and experience. Henan Provincial Coal Office chief engineer, director of Henan Coal Institute comrade Yan Jinman presided over the meeting, executive director of Henan Coal Society, mining professional committee chairman Cui
