偃龙矿区开采的山西组二.煤层属于“三软”极不稳定煤层,其突出特征为煤层松软、厚度和倾角变化大,顶板及底板松软、破碎,赋存条件复杂,开采极其困难.嵩山煤矿以多项支护技术专利为支撑,采用底板岩巷的“一巷三用”,合理选择高强度轻型放顶煤支掩式液压支架,以及综采防片帮和防冒顶等技术,实施综采机械化开采,实现了“三软”煤层的安全高效开采,取得了显著效果.
偃龍礦區開採的山西組二.煤層屬于“三軟”極不穩定煤層,其突齣特徵為煤層鬆軟、厚度和傾角變化大,頂闆及底闆鬆軟、破碎,賦存條件複雜,開採極其睏難.嵩山煤礦以多項支護技術專利為支撐,採用底闆巖巷的“一巷三用”,閤理選擇高彊度輕型放頂煤支掩式液壓支架,以及綜採防片幫和防冒頂等技術,實施綜採機械化開採,實現瞭“三軟”煤層的安全高效開採,取得瞭顯著效果.

Shanxi I1 i in Yanlong mine is a kind of coal face on" three-soft coal seam", which primary charac- ters are a soft coal face, a large variety of thickness and angles, a soft and cracked roof and bottom, compli- cated hosting conditions, difficult mined. By means of seveval patents of Songshan mine, "one tunnel, three use" , reasonahly selected high intensity and light roof coal shielding hydraulic support, preventing coal slide technology and preventing roof falling technology, mechanized mining technology were implemented creatively. Safe and high -efficiency mining and remarkable results have been achineved.
