1、龐莊煤礦初步設(shè)計(jì)摘要本設(shè)計(jì)井田面積為9.67平方千米，井田內(nèi)煤層賦存比較穩(wěn)定，煤層傾角8-10°，平均傾角9°，平均煤厚4.6m，整體地質(zhì)條件比較簡(jiǎn)單，瓦斯相對(duì)涌出量1.73m3/t，礦井正常涌水量120m3/h，最大涌水量為340m3/h。根據(jù)實(shí)際的地質(zhì)資料情況進(jìn)行井田開(kāi)拓和準(zhǔn)備方式的初步設(shè)計(jì)，設(shè)計(jì)礦井年產(chǎn)量0.9Mt/a，決定采用立井單水平加一輔助水平上下山開(kāi)拓方式，設(shè)計(jì)采用綜合機(jī)械化放頂煤回采工藝，走向長(zhǎng)壁采煤法，用全部跨落法處理采空區(qū)。并對(duì)礦井運(yùn)輸、礦井提升、礦井排水和礦井通風(fēng)等各個(gè)生產(chǎn)系統(tǒng)的設(shè)備選型計(jì)算，以及對(duì)礦井安全技術(shù)措施和環(huán)境保護(hù)提出要
