AI System for Autonomous Mining: Development and Deployment

We develop AI control systems for autonomous mining machinery. Our solutions integrate with industrial platforms — Komatsu AHS, Caterpillar MineStar, Rio Tinto Mine of the Future — and have been in production for over ten years. Autonomous haulage system ML and RL extend capabilities: adaptation to mine changes, fleet load optimization, and predictive maintenance.

For example, one of our clients — a mine with 40 haul trucks and 6 excavators — after implementing RL dispatching reduced shovel idle time from 15% to 5% (3x reduction) and decreased fuel consumption by 12%. The solution paid back in 8 months. Get a consultation on implementing AI dispatching at your mine.

How RL Optimizes Fleet Dispatching

Classic problem: N trucks, M shovels, and K dump points. Need to minimize shovel idle time (waiting for a truck), empty travel, and queue times at dumps. Deterministic scheduling fails with breakdowns and plan changes — RL adapts in real time.

class MiningFleetEnv(gym.Env): def __init__(self, n_trucks, n_shovels, n_dumps): self.n_trucks = n_trucks self.n_shovels = n_shovels self.n_dumps = n_dumps # observation: status of each truck + shovel + queues obs_per_truck = 6 # position, load_status, fuel, ETA, queue_wait, is_broken obs_per_shovel = 4 # position, dig_rate, queue_length, availability obs_per_dump = 3 # position, throughput, queue_length self.observation_space = spaces.Box( low=0, high=np.inf, shape=(n_trucks * obs_per_truck + n_shovels * obs_per_shovel + n_dumps * obs_per_dump,)) # action: assign truck to a point (shovel or dump) self.action_space = spaces.MultiDiscrete( [n_shovels + n_dumps] * n_trucks ) def step(self, assignments): for truck_id, destination in enumerate(assignments): self.trucks[truck_id].assign_destination(destination) self._simulate_step() reward = -(self.shovel_idle_time + 0.5 * self.truck_idle_time + 0.3 * self.queue_wait_time) return self._get_obs(), reward, False, False, self._get_info() 

Path Planning in Complex Terrain

A mine is a dynamic environment: blasts create pits, landslides block roads, humidity changes traction. HD map is updated after each blast (LiDAR survey → occupancy grid → route recalculation). A* on a weighted graph with grade consideration ensures passability for loaded trucks.

def mine_astar(start, goal, terrain_map, max_grade=10.0): def heuristic(a, b): return np.linalg.norm(np.array(a) - np.array(b)) def slope_cost(current, neighbor): dz = terrain_map.elevation[neighbor] - terrain_map.elevation[current] dx = terrain_map.cell_size grade = abs(dz / dx) * 100 if grade > max_grade: return float('inf') return 1.0 + grade * 0.1 return a_star(start, goal, heuristic, slope_cost) 

On difficult terrain, an RL controller adapts speed and braking — training in CARLA with a custom terrain plugin yields better results than PID control.

How Safety Is Ensured in Autonomous Equipment

The safety architecture is multi-layered. Hardware failsafe (ASIL-D) guarantees stop on communication loss. Virtual barriers via GNSS prevent equipment from leaving the zone. Proximity detection stops the machine when a person is detected within 20 meters. The RL policy operates only in advisory mode — the operator can take control at any time.

What Predictive Maintenance Brings for Mining Equipment

An unscheduled failure of a haul truck leads to 6–24 hours of downtime, losses exceeding $100K/hour. An LSTM on 45 sensors predicts failure 24 hours ahead with 92% accuracy. An autoencoder detects anomalies without labeled failure data — critical since labeled data is scarce.

class TruckHealthPredictor(nn.Module): def __init__(self, n_sensors=45, hidden_dim=128): super().__init__() self.lstm = nn.LSTM(n_sensors, hidden_dim, 3, batch_first=True) self.head = nn.Sequential( nn.Linear(hidden_dim, 64), nn.ReLU(), nn.Linear(64, 1), nn.Sigmoid() ) def forward(self, sensor_history): out, _ = self.lstm(sensor_history) return self.head(out[:, -1, :]) # deployment: threshold 0.7 → alert → planned maintenance on the next shift 

Comparison of Dispatching Approaches

Integration with MES and Dispatch

Komatsu AHS API and Cat MineStar REST API — we receive fleet status, send commands. The RL dispatcher runs as a microservice. OSIsoft PI / Aspentech Historian store telemetry for training. Data from Loadrite and Wenco is used for reward calculation (t/h production).
