用户希望我将矿车生产运营数据统计界面（最早的那个矿车运营数据仪表盘）也增加矿区/车辆类型/车辆的筛选与分组统计功能，就像刚才的载荷与生产效率统计界面那样。
回顾最早的矿车运营数据统计指标：
- 运行时长
- 作业时长（= 卸载+装载+空车返回+重车运行）
- 作业循环次数（空车+装载+重车运行+卸载 = 1次循环）
- 怠速时长
- 装载时长
- 卸载时长
- 空车返回时间
- 重车运行时间
还要保留：
- 时间区间选取
- 按年/月/天统计分析
- 显示每天/月/年的分布情况
- 装载/行驶/卸载时间占比分析
新增功能：
- 按矿区筛选
- 按车辆类型筛选
- 按车辆筛选
- 分组统计（按矿区/类型/车辆）
设计风格：白底企业级设计，与之前的界面风格保持一致。
我需要重新生成一个完整的HTML页面，整合矿车运营数据的所有功能加上新的筛选和分组功能。
让我参考载荷页面中的车辆数据结构和筛选逻辑，类似地构建矿车运营数据的版本。
关键设计：
- 5项指标卡片或8项指标卡片（根据之前的矿车界面有8项核心指标）
- 折线图：运行趋势（运行时长、作业时长、循环次数）
- 堆叠柱状图：时长构成（装载、重车、卸载、空返、怠速）
- 环形图：装载/行驶/卸载占比
- 数据明细表
- 筛选栏：分组方式（按矿区/车辆类型/车辆）+ 矿区下拉 + 车辆类型下拉 + 车辆下拉
- 时间粒度切换 + 日期区间
这是一个比较大的界面，需要仔细设计。考虑到是16:9的比例，需要合理利用空间。
让我开始构建这个界面。
我会复用载荷页面中的车辆数据（VEHICLES数组），但针对矿车运营数据生成不同的指标数据。
8项度量指标卡片可能在一行内排列会比较紧凑，考虑到16:9宽屏，可以放8列。但如果加上筛选栏可能会占空间。让我将指标卡片做成8列网格。
图表面板可以用3列（折线+堆叠柱状+环形占比），这与之前矿车运营数据的设计一致。
数据表放在底部。
筛选栏放在header下方，与载荷页面类似。
现在让我构建完整的HTML。
